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.

The sun continues to put on quite a show today with its array of active regions.  The image below shows AR1226 and 1227 with their collection of dancing filaments.   Currently there are six active regions visible on the sun, providing a lot of different things to view and image!  It will be exciting to see what unfolds over the next few days as some of these regions have been producing C-class flares.

For the last few weeks the sun has grown quiet again.  After spoiling many of us with awesome active regions, prominences, filaments, etc…  Well over the last couple days the sun has unleashed a angry display with AR1226 and AR1227 which has unleashed several C-class flares!  Solar observers around the world are urged to keep the scopes trained on the sun for the next several days.

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!

We truly enjoy seeing the images being shot with our products!  Please continue to keep sending in you images and we will put them on our blog.
