Description

Mars one day after closest approach (but apparent diameter is the same for all practical purposes).

SharpCap capture with 5ms exposure time, gain 300. (First light for my QHY5III462)

AutoStakkert!3 stack (15% of ~25000 frames)

PixInsight MultiscaleLinearTransform

Photoshop rotation/curves/color.

There are some leftover artifacts from the stacking and drizzle process. I'll likely try different settings and other recordings from the same night and see what difference they make.

Nominal focal length was 4000mm (8" F/10 + 2x extender), but calculations from Mars diameter in pixels show more around 3765mm effective focal length (note, I didn't do anything special with extender spacing, pretty much just stuck everything together and focused).
