This is my first attempt at solar imaging. Actually first time Ive visually observed too.

Image is AR707 on 28 November 0324 UT. Taken with 25 cm Newtonian stopped down to 9 cm with Baader Astrosolar filter (visual) and with my Sony handycam / 32mm Plossl and 2 x barlow. Gain = 3dB (18 is max) 50 fps @ 1/215 exposure. 42 frames stacked in Registax and some unsharp mask in Gimp. I am not sure the stacking achieves much as some of the individual frames were almost as good as this final image. Seeing about 2-3 arcseconds.

Here is another this time AR708, taken a few minutes later (03:29 UT). This time with 0db gain and 1/450 sec exposure and just the 32 mm plossl. I have added a bit of colour grin

Its very similar to one posted by Paul Maxson a few days ago. Even within a few hours there are changes to the area around the sun spot.
