The Horsehead , The Flame and Alnitak - HaO3RGB JanFeb2020

Sign in to follow this  

I managed to get some time to process another of my images exposed in January/February 2020.

This was the last image when my USB port on my Astro40D failed. This happened while imaging this scene but it happened toward the end of the imaging plan so I got almost the subs that I wanted. The total exposure time was 16 hours and 16 minutes in ISO1600 for all of the subs, RGB, (OSC through the UV/IR Cut filter), HAlpha and OIII.

Imaged through my 8" SCT at f6.3, 1280mm FL.
