Alan,

Very nice detail.  Do you put the four frames into layers in PS and then put them at 25% opacity to get an average effect before flattening them?  And I see you have a 6" AP refractor as well!

Hi Jim,

I thought I was the only one crazy enough to be shooting the sun through the clouds... but at least I had enough sense to pass on Ha! 8^)

I made this picture of solar archipelago 1109 by averaging four frames from one video in Photoshop. Sometimes that works better than stacking.

Well, not the most exciting solar image but I did have to dodge several hours of clouds this Sunday morning to get it. This was taken with the improved 80mm PST mod scope that I had put together this past winter. My AP Traveler is otherwise occupied so I sprang for a cheap used $60 Celestron 90mm f/11 achromat, cut off 13cm of it and installed an even cheaper all plastic Meade 2" focuser. Despite humble origins, it works quite well. The addition of the BF10 (BF5 is stock with the PST) I get a much larger fov and less of the troublesome internal reflections. So I get the resolution of an 80mm solar scope with the internals of a PST etalon.
