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

Very nice details. You are a little bit on the magenta side - try adding a little green to the mix by either lowering the white point for green (drastic approach) or use color balancing in Photoshop to boost the green mid-level a bit, and drop the red a bit. I used 0.86, 1.05, 1.08 for the red/green/blue mid points and got what I think is a little better color balance.
