Description

My first look at Mars since 2018. Both seeing and transparency were fair, but not good and not helped in that Mars was at only 25 degrees, right above the roof my house and the rolled back roof of my observatory, both no doubt still radiating the heat from the day.

The image is an IR-RGB image, IR used as luminance to enhance surface details, being 50% L de-rotated in WinJupos.

Data is all 20% of 3x5000 frames for RGB and 10,000 frames IR.

Altitude: 25°

Diameter: 16.1"
