hi all,
here's an image of ngc 3623, part of the Leo TRIO. Taken with an orange tube (old) C-8, and a ST8-E camera. LRGB 70:10:10:10 minutes (L 1x1 bin RGB 2x2 bin . L and RGB processed in MaximDL and 8 bit jpegs were LRGB combined in PaintshopPro. The moon was out so some wicked gradients resulted in the raw images ... I did the best I could to remove them ...but if you look they still there.
The raw FWHM of the images was 2.4 arcsec and after 3 iterations of ccdshararp it came down to 1.9 arcsec.
clear skies,
Larry Citro
