Description

Bortle 7 urban skies. Excellent guiding at 0.4-0.5as/px (matched perfectly to the 0.5as/px resolution of the ASI6200MM on the RC8 with its 1624mm FL).

Testing out my new ASI6200MM in my RC8 - pleasantly surprised to find that the full frame sensor was fully illuminated with pinpoint stars right to the corners (using a TS Optics RC field flattener).

Tried to process without blowing out the brighter stars (which is a common sight on Astrobin) - makes the star density of the region look a little less intense but to my eyes allows for interesting structural details to emerge.
