Sky and Telescope Hot Product 2010!!

We certainly appreciate being recognized by Sky and Telescope for a Hot Product of 2010 Award.

This award has been presented to Lunt Solar for the LS60T/Ha/PT system.

The Pressure Tuned System received an overwhelmingly positive response when shown at NEAF, RTMC, and PATS in 2009. I will be writing a full editorial about the Doppler True tuning system with insights into how to get the most from this system, and why this new technology is such an innovation to the Solar Telescope.

Thanks again to all the folks at Sky and Telescope for picking Lunt Solar and the LS60T/PT. I am very proud of this scope and enjoy testing them every chance I get.

Great Activity Today !!!

Tucson, Arizona has cooled some from last week. One week ago today it was 90 degrees, today we are in the low 70s.. oooh that's chilly...

Along with the cooled temps has come some nice transparent skies. I was testing today and I am very delighted to see several good active areas and as many as 4-5 small developing areas. In addition there are filaments on the surface.. woooHooo!

I hope you get a chance to get outside and view, it's very nice to see the significant increase in activity over the last few months..

Let me know what you see..

First Week of November (Last Part)

As of November 1st we officially began to move into our new expanded facilities next door. Our landlord, Steve, has been nice enough to let us store our cases, shipping containers etc. over there for the last few months until the facilities were ready. The new facilities increased our square footage by about another 40%.

The expansion incudes a few more offices, a nice education/AV area with kitchen and restrooms, and in mid area a nice big fully climate controlled room for our upcoming coating facilities with large double doors to our current assembly area. The back of the area has been heated and cooled, but is currently used as a main storage area. During the buildout of our current area, we had the fore thought to put 800 Amps of 3 phase power in, so the new area has plenty of juice to keep us going.

I'll have to get some pictures up, but it's hard to believe that we first moved in to the current building in February of 2008. The building had a small kitchen, and a lobby. There were NO bathroom facilities. (We made friends with the neighbors very quickly ;). The first 2 Continuous Polishers were working in the kitchen area on very long extension cords. I had an electric heater on one wall and an air conditioner on the other, both fighting to keep the un-insulated room at +/-1 degree.

6 months later we were able to move out of the kitchen and populate the new building just in time for our open house..

14 months later we are still expanding and I am still working very hard to increase our capacity to meet the ever growing demand.

First Week of November (Part 2)

During this week we finally finished our 6th Continuous Polisher.

All the polishers at Lunt are custom designed and fabricated on site. They are currently all 48" diameter with a capacity for about a 12" part. In our application we use plastic fixtures on the lap to hold multiple sizes. We also utilize a large conditioning wheel that runs continiuously on the lap to maintain the required flatness to the parts being polished.

The 48" granite lap is supported on a thick steel plate which mounts via a very heavy duty machine bearing to our custom tables. Our tables are designed and manufactured to be very solid. The lap is driven by a 5HP motor with a large gear reducer, all controlled by a variable speed controller. Due to the fact that our laps generally run 24 hours a day, 7 days a week, we have ensured that all components are over sized for the job.

The granite forms the solid and thermally stable foundation for the polishing pitch. We use a Gugolz fine pitch. We heat the pitch up in a very large pot and once fully liquid, we add secondary components to ensure that the lap will remain firm and stable for long periods of time.
These additions make the lap very "hard". The trade off is that it takes many hours just to push a lap 1/4 wave in each direction. The benefit is that the lap remains flat for extended periods of time, allowing us to finish an entire batch of glass in that timeframe. This also ensures that the laps cannot drift too far while being run overnight. The hardness of the lap and the fine polishing compound assure that our flats are very precise and have no roll off at the edge.

Our next project is the fabrication of a 36" Continuous Grinder. David, our glass grinder, spends 8 hours a day grinding glass from rough cut to fine grind. A second machine will allow us to provide just a little more ground parts than the optics shop currently needs freeing David to hekp in other areas.

In addition to the 6 48" CPs, we are in the middle of construction on our 72" Continuous Polisher. The granite has arrived, and the steel base is finished. This machine will be used to manufacture precision flats up to 24" in diameter. Recent large flats were finished on a large draper style machine. Although we eventually met the specifications of 1/10th wave over 20", we have certainly concluded that a large CP is the way to go.

Outreach in Riverside, CA

I wanted to share my experience with this new gear.

I don't know what Andy does when he matches this scopes and filters up but I am just completely blown away by the views with the new LS60THa scope and my original LS50FHa filter. This set up starts to mimics views I had years back with a buddies older Coronado Solarmax 90 filter on a TV101 scope! I knew double stacking was the way to go but seeing it real time with this latest technology really reinforces it.

I got first sunlight Saturday morning and could see so much detail on a new emerging active region that day. The bright spot with detailed twisting was very easy to see and study. The orange peel was so intense that the sun's globe was starting to show the classic 3D quality of truly high end H-Alpha rigs. And, amazingly, the double stack even at 50mm aperture was still able to show the prominences extremely well even while showing all this surface detail. How can this be!!? Most smaller aperture double stack H-Alpha filters and scopes in the past just showed higher surface detail at the strong expense of easily seen edge detail. Not both at the same time. This little additional gift to the views is just more iceing on the solar cake.

Using the scope and filter set up at the large STEP Conference outreach here in Riverside for the last two days presented easily seen surface detail for every single student and teacher. Every single one. No guessing. There was never any......"well I see it sort of but I'm not sure". Even the younger children could view the orange peel, filaments and active regions clearly. Lots of smiles or "that's so cool!" or "that's really our sun? Are you kidding me?....awwwwesome!!"

I now have the ultimate solar outreach tool that can be use to share our star with many thousands of the public of all ages over the years. I have tools to do serious outreach all day long. Not just at night. For an outreach junkie like me this is true Nirvana.
I thank all of you guys involved at Lunt Solar Systems for bringing this company to market. You folks really are continuing the vision of bringing H-Alpha observing to the masses. All I can say is your service and products speak for themselves.

.....Thanks for these very kind words, we look forward to hearing about ongoing outreach from Riverside and in your area.....

Thanks again,
P. Agins

The NEW Website!!

The new Lunt Solar Website is almost finished!
........It is almost finished... right?..........

With DNS transfer scheduled for Wednesday, November 11th I am excited about finally starting on a website dedicated to everything Solar. With live streams in Ha and CaK, news and events, forums, galleries, and editorials provided by the users of solar equipment.

We would like to see Solar enthusiasts get involved. Jot down a few stories, ideas or experiences and submit them for the site. We will be featuring articles on past and upcoming events, your local outreach efforts, and a chance to share you knowledge of observing and imaging. And please include pictures!!

The new community area will be dedicated to everything solar it does NOT matter what brand of scope you use. I have been involved in the solar filter business since about 1998, I understand that Lunt is not the only manufacture of Solar equipment, the fact is we all share the same interests and should do what we can to promote the hobby of Solar to everyone. I am certainly proud of the equipment I helped produce before Lunt, and it is a result of that experience that I am able to push it's continued evolution..

So put pen to paper and submit "articles of interest" to editorial@luntsolarsystems.com

We also need to get the word out about the new website and the blogs (there are 11 of us in this area).

The blog will be attached to the new site once the site is live..

First Week of November (Part 1)

The first week of November has flown by. A week ago today we were getting ready for Holloween night, it'll be Thanksgiving before you know it!!.

Testing, new products, and website were the projects of the week.

The image at left is the New LS152T/PT. This is currently the largest dedicated telescope that we manufacture. This is a working prototype and was on display at PATS. It had been my intention to take it outside on the Sunday, but the mount that I was going to borrow was sold on Saturday. I did try the mount it was displayed on, but that was a drop waiting to happen.

The internal lens sets for the system are almost finished. The prototype lenses were "off the shelf" and weren't quite optimized for the system proviving only about a 70% sweetspot in the center of field. The production lenses have been designed to the optical system. They are also slightly larger than the prototype given more aperture to the beam.

The LS152 contains an unobstructed 60mm HR (high resolution) etalon. This is a new etalon design and provides for high signal to noise ratio which greatly darkens that background allowing for stunning contrast on edge details.

I have already had one person ask about the unobstructed 60mm, and before the questions are raised and the assumptions made in other forums, I will state that we will not be introducing the LS60F until Summer of 2010. Due to the very high demand for the other products, we will not be tooling this particular size at the expense of current production. Our LS60F production is currently limited to the LS152T, and takes the place of the production schedule for the LS200T.

The estimated US$ retail for this instrument is $7,495.00 (this does NOT include the CaK module). For those that have the LS200T on order you will be receiving the LS152T at no additional cost. If you purchased the CaK option for the LS200T you will also be receiving that at no additional cost. As you know, the LS200T was introduced at 5k. It was the intention to increase this price once the system was shipping and had good reviews. As I will explain in another post, the LS200T could never meet both the performance requirements that I had set for it, while also meeting the strict safety requirements. The trade offs were leading to unacceptable compromizes on both sides. Safety will always be of the highest priority to ANY solar product.

For those that choose to accept the exchange, I promise that you will be receiving a solar system that exceeds my expectaions for what the LS200T was going to do. By defualt the delays have allowed for the incorporation of a 60mm etalon instead of a 50mm. The new HR (high resolution) coatings will be incorporated standard, and the value of the package itself will provide a good return on investment should you ever choose to sell.

For those that cannot accept the exchange, we will refund any deposit in full.

Recent Trip to Mt Lemmon Sky Center

This image was recently e-mailed to me from my Landlord. He and a group from his church spent the day and part of the evening at the Mt Lemmon Sky Center.
For those that attended the Open House at Lunt Solar a year ago, you will remember the visit to 9,000 ft. It was about this time of year and although the weather was clear and sunny, the temperatures were very cold.
Shortly after the visit we donated a LS100T/PT to the facility in appreciation of their hosting the event and providing everyone with a look thru some of their large scopes. Everyone had a great time.

We chose the LS100T/PT specifically because of the high altitude. A large aperture scope in great skies without the issues of air pressure to the air spaced etalon.

I hadn't given much thought to the scope on Mt Lemmon until I received this picture. Steve and the group were wandering around the domes, when Steve recognized the name on the 100T. He'd never actually looked thru one of my larger scopes before and expressed his excitment at having the chance to look thru one of our systems "in the wild". He was very pleased with the view. Everyone in the group had a chance to view the active region of last week.

This scope was provided to allow the Center to provide visitors a chance to view the Sun. The Mt Lemmon Sky Center is open to the public, and often receives large groups of children and adults who are interested in learning more about astronomy as well as the nature of the mountain.

For more information on the Sky Center you can visit http://skycenter.arizona.edu/

The facilities were remodeled about a year ago and I have to say that they did a fantastic job. From large kitchen areas, to private bedrooms, and a first rate meeting/audio visual area.

We are hoping to visit the center at our next Solar event which is now tentatively planned for March 2010.

Pressure vs Doppler Shift (Part 3)

The diagram at left shows the system has been fully pressurized. This pressure is equivalent to about a 12,000ft altitude change.
The air inside the sealed chamber has been compressed due to the reduced volume. As a result the refractive index of the air has increased and caused the CWL of the etalon to move to the blue or high energy side of the Hydrogen wavelength.

Due to the fact that there is no tilt involved, the image field remains flat and very precise.

Traditional tilting allows the Doppler shifting across the field in a plane perpendicular to the axis of light. The user can see a change to the image that allows for the viewing of proms and then filaments. The optimum position is when the proms and surface are both fairly detailed. Overtilting will tighten the bandpass but will also produce a banding effect. The resolution under the band is higher, but at the expense of the entire field of view.

People often feel that the entire field should be as good as the area created under the band. If this were possible, the systems would be spec'd at a much lower bandpass. If a band occurs, the system has probably been over attenuated.

True Doppler Tuning allows for a shift into and away from the user. Adding a 3D component to the viewing experience.
While it has minimal effect on proms due to their being at the edge of the disk, it does have an effect on filaments and active regions.
While looking at a filament at the center of the Sun the user has the ability to Doppler shift from the base of the filament to the tip, following the filament thru it's structure toward you and away from you. Allowing for enhanced visual and imaging capability for the observer as well as a research tool for the avid hobbyist.
The tuning system provides an order of magnitude more precision to the tuning of the desired features.

We are working on designs to the LS100F and the LS100T/Na utilizing the same technology.
The LS100F will be remotely operated for those that have this filter mounted on a long FL scope and do not have 4ft long arms.
We are currently manufacturing the LS60T and the LS100T via this technology.
The LS60T is fully upgradeable to the new Pressure Tune System at any time. However, it does require a return to the factory.

End of Part 3

Pressure vs Doppler Shift (Part 2)

The diagram shown at left indicates that the air pressure inside the sealed chamber has been increased. At this point the CWL of the bandpass is at 656.28nm. At this position we are looking at the Hydrogen-alpha line and the energy associated with that wavelength.

The sealing of the cavity is done via the collimating and refocus lens so that the etalon itself is isolated from differential pressure.
The piston applies from zero to a pressure that is equivalent to taking an etalon from -500ft to +12,000ft above sea level.
This has the added benefit of making the etalon system altitude insensitive.

In addition the etalon can be used from -50 to +200 degrees Celsius due to the fact that the tuning can compensate for the very small changes that heat would have on the "feet" of the etalon.

I have gone into great detail in prior posts regarding the compromises of tilting internal to a telescope. Only very small adjustments to the tilt of an etalon can be done otherwise the etalon system will begin to suffer from the off axis rays of the re-collimated beam.
People have noted that in internal tilt systems the CWL is very sensitive to even small adjustments of the tilt wheel.
By removing the need for tilt we have placed the etalon in the most optimized position possible.
We install a very accurately tuned etalon. This etalon is tuned to the red side of the CWL. Given that it is already tuned to the red, the user has the ability to shift the tune of the CWL to the Hydrogen-alpha line and then Doppler tune to the blue or back thru to the red.

Due to the fact that there is no tilt involved, the image field remains flat and very precise.

End of Part 2

Pressure vs Doppler Shift (Part 1)

Lunt Solar Systems recently introduced the new Pressure Tune system, or Doppler True Tuning system.

The image at left shows the basic outline of this system. The internal etalon is at ambient pressure. The tuning of the etalon is slightly low, putting the Center Wavelength (CWL) at the red wing of the Hydrogen line. This provides a view of less energetic features in the Chromosphere.

How does it work and what does it do?

The system works because the etalons used in the current Lunt designs are air spaced. These air spaced etalons have been typically tuned to the Hydrogen-alpha line via several mechanisms.

The first is the spacing of the air gap between the high reflective surfaces of the ultra flat plates. By changing the spacing, you change the CWL. The distance of this spacing is generally held constant because the refractive index of the medium between the plates (air) is relatively stable at ~1.
The center wavelength can be manipulated from there by slight tilting of the etalon. This changes the angle of the light at the interface of the high reflector/air layer, having the effect of moving the center wavelength toward the blue.

Slight changes in barometric pressure and/or a change in altitude will effect the CWL due to the change in refractive index of the spacer layer.
These changes can be compensated for by additional tilting provided that the etalon is tuned to accomodate those changes.
Taking an etalon that was tuned at 100ft to 10,000ft would certainly not be within that range.

In the past I have manufactured sealed etalon systems for space flight.
These etalon systems were designed to work in a sealed vacuum. As a result they were manufactured as very highly tuned etalons. By placing them under vacuum, the tuning lowered . Tuning was done to ensure that at full vacuum the etalon was on band.
Additional fine tuning from there was done via heat due to the fact that the vacuum could not be adjusted.

Our technology utilizes air pressure and not vacuum.

Lunt Solar and our new Website

On November 12th Lunt Solar Systems will be taking it's new website live.

I know that most of you are thinking that it is about time. I couldn't agree with you more.

The new launch will coincide with another very exciting announcement. As a result, Lunt Solar and it's products will be recieving some significant media attention. At the moment this other announcement has to be kept under wraps, but I assure you, it will be worth the visit.

The new website will be far more of a monthly magazine with focus on Solar events and activities. We are introducing an interactive community area and are looking forward to having editorials and blogs from customers and solar enthusiasts. We certainly hope that you will check back often and will participate.
Our goal in 2010 will be to introduce and develop an educational and learning source that will provide resources to all ages for everything Solar.

We are just finishing up our Live Solar feed in both Hydrogen-alpha and CaK, and although we anticipate being able to begin the live feed on Monday, November 2nd, we will bide our time and wait for the new site.

In addition to the above, Lunt Solar is going digital. We will be teaching ourselves the imaging process. I will be blogging our successes and failures, and I hope that very soon we can begin to provide a diary of images of the Sun's growing activity toward Solar Maximum. (we may need just a little help along the way).

Soooo, put your thinking caps on and type a few paragraphs for the new blogs. We would be interested in upcoming events, outreach activities, and anything solar related..

We also need you images for our upcoming new gallery. Please submit your images to blog@luntsolarsystems.com. Include a brief description of what equipment was used and how, where it was taken, and the name of the person to thank. Images of people looking thru and using solar equipment are also welcome.

More to come..

R&D Projects at Lunt Solar Part 1

It's probably doesn't come as any surprise that Lunt Solar Systems LLC is involved in R&D projects outside the field of Solar Filters and Telescopes.
But it is because of our highly technical and specialized skills that we are often asked to develop unique optical elements that fall within our capabilities and my interests.
Some of these R&D programs are confidencial. Some of the ongoing projects are not, and may not only be of interest, but they may encourage readers to suggest other uses for these technologies.

One of our more recent projects has been the developement of a novel solid etalon design.
The intial concept was for the design of an ulta thin, ultra stable, ultra precise, and ultra narrow bandpass micro etalon.

The project's scope of work consisted of manufacturing a solid etalon that was approximately 0.3mm thick (0.012") at the Hydrogen-alpha line.
Multiple matched etalons needed to be produced. The desired size was 4mm x 4mm.
The Hydrogn-alpha emission line was chosen due to our knowledge of manufacturing at that specific wavelength. However, Hydrogen-alpha is not the desired wavelength of the finished product.

The results have been extremely succesful.

At Lunt Solar we produced what can essencially be referred to as a wafer etalon.
The solid etalon was manufactured from a 80mm piece of low expansion UV grade material. (not zero expansion).
The "spacer" layer was polished to 0.3mm thick and send out for testing prior to further work. We needed to show verification of the spacer layer's precision prior to going to the next step.

Results:

The Wafer was first tested for surface flatness. Surface flatness was not the concern given that the etalon would be used in transmission.
It was the Transmitted Wavefront that was specified.

As you can imagine the wafer did suffer from some surface error due to being held in a fixture.

The surface flatness was measured at 1/6th of a wave, some of that coming from astigmatism due to the fixture point.
Power was the major contributing factor to this error due to the method of manufacture.

The Transmitted wavefront results were very encouraging.
The interferometer showed a peak to valley error over 75mm (the aperture of the system) of 1/61th wave at 532nm. The RMS being better than 1/250th wave (the limit of the test system).
This test was over 75mm. The system was not capable of realizing a measurement over 4mm aperture, and the engineer was not able to speculate just what that result would be could it even be measured.

These results were followed by some interesting conversations with the test facility who wanted to know how we had tested the wafer ourselves.
For those that have visited Lunt Solar in Tucson, you will know that I test ALL optics for flatness by eye only.

The wafer was sent out for coating via a low temperature, ion assisted process. The wafer was coated on both surfaces with what I now refer to as the new hybrid high reflector.
Some initial tests needed to be done to assure a "tune" at the desired wavelength.
In this case we tuned slightly low of Hydrogen-alpha in order to utilize the standard method of heat to bring the etalon accurately on band.

The end result was a pellicle wafer of about 80mm diameter. Given the highest degree of precision for the entire etalon, we could now be assured of matching etalons of 4mm x 4mm after the wafer had been diced.

The net result as far as specifications go are as follows:

Bandpass: 0.2 Angstroms
Free Spectral Range: 11 Angstroms
Finesse: 27

A few technology applications immediately come to mind given the controllable FSR and the narrow bandpass. I would certainly like to hear your thoughts on possible applications as well.

I am obviously excited about the prospect of getting this system assembled into the back end of a SCT telescope very soon. The wider acceptance angle of this design vs a conventional higher index spacer material will make the modification to existing SCTs in the market fairly simple and compact.
The fact that the etalon itself is thin and has little mass will allow for rapid temperature change and stabilization.
The use of the proven materials will allow for a mass-produceable 0.2 Angstrom bandpass system with a single etalon. I can hear the calls for a double stack system already...

Moving outside my area of expertise and free thinking for a moment...

The product is of a robust solid design and the CWL of the system can be fixed to a specific wavelength or tuneable.
The thickness of the system lends itself well to the bonding to CCDs. Maybe multiple etalons can be bonded to a single CCD to provide a chemical signature detector?
I have thought about it's use in applications such as ionized gas/chemical detection for a while.

Used in these applications the signal to background noise ratio would be of huge advantage, eliminating all background noise and providing >90% T at the desired wavelengths.

We provide 0.5A bandpass looking directly at the Sun. Ambient daylight would be of no issue.

Ancillary light sources such as laser or short wavelengths could be used to further excite the desired compounds?
Are there military applications for ionized gas/chemical detection for munitions, gunfire etc?? The addition of signature trace elements to munitions that can be optically traced?

Other applications may include laser line stabilization, optical fiber multiplexing, etc...

This is just one of our current R&D projects. It is thanks to this project and a few others which I will outline in another blog that we are rapidly improving the performance of our core products. Success and failure though our ongoing research projects are already seeing a positve impact on the contrast and resolution of even our most basic systems..

Upcoming products will focus on enhanced performance and the ability to accessorize systems for use as educational tools.

I encourage your feedback and comments and thank you for reading.

The Beginning of a new Solar Maximum

The Sun is our Star, and as you would expect, our Star is hot, bright, dynamic, and sometimes quite violent.

At 93 million miles away, we are ideally placed at a point where the Sun provides just enough warmth and energy essential to our living planet, Earth.
At only 93 million miles, the Sun is close enough for us to view it's surface thru a relatively inexpensive scope from the comfort and relative safety (Sunscreen please) of our backyards on a clear and warm day.

What! Astronomy during the day? Lunt Solar can show you how.

To a growing many, daytime observing is the only time they can see a Star. To teachers it's an ideal way to bring the science of a living Star to school kids, and to parents the exploration of the Sun shared with their own children. No more staying up until 2AM in the pitch black and potential cold to visualy view pinpoints of light.

What's more fun than looking at that fireball at the center of our own Solar System?

For the thousands of people who already own a Solar Telescope you've already had a hands on appreciation of the dynamic nature of the Sun's daily cycles.
Given that the hobby of Solar observing really didn't become mainstream until the late 1990's, relatively few have probably witnessed the ferocity of a Solar Maximum.

For those that began the hobby in the last few years, you may be wondering what all the fuss is about.

The Sun has been at a slightly extended Solar Minimum of about 1-2 years. This is a time of reduced Sunspot and Flare activity. Being a living Star, the Sun's activity "breathes" in and out over a period of about 12 or so years.

The Sun has been holding it's breathe.

For those that are interested, Solar Minimum is now over, and the next Solar Maximum has already begun. Getting a Solar Telescope delivered by Spring maybe just in time.

The Sun has begun to let it's "breathe" out. As it does so over the next few years, the Sun will become far more active. There are already daily signs of increased Solar activity. My daily observations compared to 1 year ago clearly indicate an increase in daily Sunspot count, Prominence activity, the apprearance of Filaments on the surface, Active Regions, and even the rare Mass Ejection.

So how do you see the Sun?

Although the core technology, or the Etalon, of Solar Telescopes has not changed over the last century, the idea of actually looking at the Sun didn't catch on in
the mainstream until the late 1990's. Before that time, Solar observing was left to the "professional" elite who paid out 10s of thousands of dollars for the precision optical systems required.

Over the last 15 years, the price of a Solar Telescopes has dropped to a point where the "amateur" can make the choice between a good nighttime scope, or a great daytime scope. Even today's basic Solar Scopes are by far the most advanced ever made.

With entry level Solar Telescopes at $600, and the well fitted LS60T/PT at $1400, the ability to enter the rapidly growing hobby can be achieved by many, and before we make a comparison to that nighttime scope, lets not forget that the LS60T
contains 17 precision aligned filters and optical elements that provide redundant 100% safety allowing us to view the Hydrogen-alpha emmision line (ionized Hydrogen)
at a bandwidth of less than 0.7 Angstroms (the spectrum is 7,000 Angstroms wide), while reducing all other wavelengths to absolute zero.
That night time scope has 2, maybe 3 lenses/mirrors.

Clubs and events are popping up everywhere. Solar viewing events are being paired with nature viewing events like hiking and birding.
Many cities have yearly science expos where Solar vendors are now showing and discussing the latest equipment, technology, and current solar events.
Solar forums are growing. People are learning to image the sun quickly and easily with simple camera equipment, while others sketch what they see visually.

Education and learning thru hands on observing.

Over the next few months and year, we will be working on promoting the Solar Community thru our new web magazine at www.luntsolarsystems.com. Providing education not only on the use of our Solar Telescopes and Equipment, but also the education of the science of the Sun itself and it's effects on our planet.
