Description

I decided to download the final set of free data offered through Deep Sky West's remote observatory, and then try to process it. The data they provided was really good once again - although I preferred the M31 data - that said there were a lot more subs for M31.



I processed 19 subs in blue at 300s long each, 18 subs in green at 300s long each, 18 subs in red at 300s long each, plus 13 subs in luminance at 300s long each. I also used the additionally provided 8 subs at 60s and 8 subs at 120s for a HDR composition for taming Alnitak. As with M31 everthing was processed in PixInsight. Total integration time was 6 hours and 4 minutes.
