Thanks for sharing your work, Chris. Matches what I was watching this morning in my LS60. That filament in the last image was a shocker at first; it looked like a dark hair on the diagonal. But at 106+F (125 on the concrete pad) down here in Marana, I just snatched gazes and got out of the heat. I only got the scope to augment public star parties, but this is doggone fun.

What you will see here is that the Calcium image shows many features that are usually very difficult to see in conventional white light shots, and many brilliant chains of tiny points of light over the images. The Hydrogen shots next to them show the magnetic field lines better, and can reveal Doppler shifts in features as well: http://www.schursastrophotography.com/solar/sol090411.html Hope you like this comparison. This was First Light for the new Lunt refractor!
