Description

This is probably the last image from my Intes MN56 - sob sob.

What an amazing Mak-Newt scope for visual astronomy, AP and 'green; APOs needed to match or beat it. But with the small secondary and screws on the focuser, imaging has its problems, but I still like to use it. Flats with such a small secondary look like I have 4 OAGs in the train, such is the vignetting!

This is the Leo Triplet, about 6 hours (check stats to be sure) mixed with 120s subs and 240s subs. Gain was 233 (out of 2000), so approximates about 8k FWC and 11.5 stop DR, similar to ASI 1600 gain 75.

Minimal processing, letting Astropixel Processor do nearly all the work with careful settings choice. In PS, I use colormancer for gently noise reduction, HLVG for green noise remnants and match color for slight saturation boost. That is it. Enjoying the gentler processing of half-decent data and APP is really great.
