Weather is still bad, but this Sunday's morning skies cleared for couple hours. I decided to test newly updated SharpCap, Autostakkert and new AstroSurface on Coronado's images. I regret that got Coronado PST instead Lunt few years ago. Biggest disadvantage of Coronado PST is co-called sweet spot where protuberances and chromosphere both look good and not oversaturated. Double-stacked filter makes the task even more complicated because it has its own sweep spot, so getting good image is not easy. Many guys suggest to use layers (one for the surface, another - for the protuberances), it decently works but leaves bad test of illusion. If you going to do it-do it at once
Anyway, updated SharpCap gets better and better, many new nice options, the same to the updated Autostakkert (the program is much faster and do not crash several times a day as previous version). But my biggest impression is AstroSurface - I am pretty impressed. For the Moon and the Sun Autostakkert gets better job in alignment and stacking, you can manually set up alignment points unlike AstroSurface. I noticed a very nice option in AstroSurface - Van Cittert deconvolution for the Moon and Sun, helps of lot before wavelets.
I decided to make B&W image, do not like fake colors for the Sun. The image was processed in AstroSurface only, cosmetic - Pos Free Photo Editor.
