Check out this recently captured image of AR1236.  This image was captured by Howard Eskildsen using a LS B600 CaK module on a Orion 80ED refractor.  The CaK filters do an exceptional job for viewing the plage areas around the sunspot as it can clearly be seen in this image.  Another feature that is a little bit rarer is the “Light Brigde”.  The light bridge can be seen between the main sunspot, as small and slender white line dividing the sunspot.

Excellent job Howard!

Calcium K (Ca-K) Telescopes and Filters are used to study the wavelength of 393.4nm. This emission line is one of 2 that are produced by Calcium just at the edge of the visible spectrum in a layer that is slightly lower and cooler than the layer viewed in Hydrogen-alpha. The emission line displays areas of Super Granulation Cells that are brightest and strongest in areas of high magnetic fields such as sunspot activity and active regions. Having the ability to study the Calcium K and the Hydrogen-alpha line provides important insights into the structure, strength, and depth of these active regions.

The Calcium K line is centered at 393.4nm. This wavelength is considered to be slightly outside the visible spectrum on the UV side. While most people can visually see the violet color of the wavelength, many cannot resolve the contrast due to yellowing of the cornea. People who have had cataract surgery are often able to see considerable detail. But, it is for these reasons that the Ca-K line is typically studied via the use of cameras which are able to provide stunning details.

Internal narrowband filters allow for a <2.4 Angstrom bandpass. Primarily an imaging system due to the difficulty of many to visually see everything that CaK has to offer.

Stephen Ramsden of the famous non-profit Charlie Bates Solar Astronomy Project snapped these two amazing images this morning using some of his personal Lunt gear.

This awesome image was captured with Stephen’s LS80THa single stack and a DMK41.  Detailed views of prominences, active regions and filaments can clearly be seen across the solar disk!  While things in H-alpha looked awesome the view in white light was also quite a sight!  The image below was captured using an Explore Scientific 127ED Triplet Apo. refractor using the Lunt 2″ Solar Wedge and DMK41 camera.  The crisp views of the granulation and awesome detailed images of the collection of sunspots makes this a truly awesome image!

The weather is finally in the lower 80′s and being outdoors this time of year feels great. The heat is gone.

The skies were clear and transparent. Several of the local High Schools had put on a craft fair and car show. This was done to raise money for the School Graduation Fund. The fund was created so that graduating students could have a safe, drug free party to attend.

My wife Jennifer was attending the event as a vendor. She is a Licensed Massage Therapist that specializes in Prenatal and Sports Injury management.  (luck me :) She was offering chair massage to all the stressed out parents..
I was initially just planning on helping out with the booth, but saw a great opportunity to do some educational outreach with the kids. Unlike typical astronomy events that I attend, it did take a little more encouragment from me to get people interested in the solar scope. However, a few ooowws and ahhhs later, I had a short line of takers. For those that could observe this weekend, you also had a chance to view a fairly active Sun..

The mascot above is the Tucson Toro. The Toros are a local Baseball team.

While I know that most of the kids that took a look thru the scope had never looked at the Sun before, that is to be expected. I like to provide just a little education about the Sun while they are looking thru the scope.. Wether they know it or not, they will walk away with just a little more knowledge.

This gentleman came over to take a look.. He was amazed at what he saw and I loved his comment.. “I am 71 years old, and there is very little I haven’t seen. It’s always a great day when, even at my age, I get to experience something new and wonderful”.
For about the next 20 mins we chatted about everything Solar. About 10 minutes after he left, another couple of Sheriffs came by. They had been told to check out the scope at the school.. Very cool!!

All in all it was a great day. I have been invited back to do some “SAFE” outreach events. I am probably going to put together a small presentation about Solar education and some Solar safety tips…  

I would certainly suggest that anyone who owns a Solar scope and a small mount go out to their local events and simply set up. It’s a great way to share the hobby and make connections with people in your community.

One such sketcher is Alan Strauss.  Alan has become a well respected solar sketch artist on the forums of Cloudy Nights, posting a sketch nearly every morning!  Much of Alan’s work is done through his LS60THa/PT and his TEC140ED with a Lunt Solar Wedge for white light.  His sketches truly capture an impressive amount of detail!  Detailed surface detail, strong active regions, dark filaments, and raging prominences can all be seen in his sketches, much like a CCD image!  Below is one of his sketches through his LS60THa/PT.

While Alan does much of his sketching from his home observatory, Lost Pleiad Observatory, he does bring out his gear to some of the larger Arizona star parties.  I had the pleasure of meeting Alan and his good friend and observing partner Jerry Farrar at the All Arizona Messier Marathon in March 2010.  Both of them spent nearly an hour and half sketching through the LS60T, TEC140, and LS152T making sure they caught every last detail!

(One of Alan’s White Light Sketches)

Though Alan spends a considerable amount of time under the sun, he also does a lot of deep sky work, sketching galaxies, nebula, and star clusters; all of which can be seen on his website (click the link above).

Sketching takes time and practice like anything else, Alan gives thanks to his observing partner Jerry Farrar for teaching him the ways of sketching and observing. Alan plans to continue his sketching, always refining his techniques and constantly learning.  He hopes to one day upgrade to the LS100THa which will provide even high resolution and help capture finer details!

Sketching is indeed an art, it requires patients and a steady eye.  So give it a try next time your out on a scope!  Even just a basic drawing of what you see, this can help with further observations, maybe through different scopes, different filters, and different observing sites.  Most importantly, go out and have a good time!

Here is a bit of info… The image is shown with the optional DSII added.

1) The DSII will soon be available on ALL Lunt dedicated scopes including the LS152T!!

2) This same module will also be available as a rear end addition to the Celestron C11 and C14. This package will include the Lunt True ERF to safely aperture the scope to the appropriate size, removing both UV and IR energy from the optical path.  A straight thru BF will be integrated into the module for enhanced viewing.

The LS80T/PT (pressure tuned) is a complete and dedicated Solar Telescope with an Image Scale of 408.  Image scale is calculated by the effective image size at the focal plain and the clear aperture of the scope.  A precision aligned ED refractor with a fully un-obstructed 80mm optical aperture. This package provides a significant step up into the Intermediary category of Daytime Solar Observing, Maintaining the most advanced technology of Doppler True Tuning for fine adjustment of the center wavelength, allowing research of the Sun’s disk and surface details at increased image scale.  Prominences, flares, super granulation, filaments, and active regions will be observed.

The LS80T package is fully upgradeable with several options including the NEW evolutionary Dual Internal Stack Etalon System (DSII). The DSII eliminates the need for an external doublestack etalon reducing cost and eliminating obstructions. The system is 100% un-obstructed. The bandpass is reduced to <0.5 Angstroms. See the Sun’s weather in stunning high definition.

True Doppler Tuning allows for a shift into and away from the user.  Adding a 3D like 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 on the surface.  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 pressure tuning system provides an order of magnitude more precision to the tuning of the desired features.
