Andromeda Galaxy, OSC from Bortle 8

[Lee_P]

You know we're into autumn when Andromeda Galaxy photos start appearing! This is 24 hours of data from Bristol city centre, OSC camera, no filters. Tough to edit, I hope to add some L-eXtreme data, and improved processing skills, next year. More info: http://urbanastrophotography.com/index.php/2021/10/04/the-andromeda-galaxy/

That is a ton of detail from the city with no filter, Lee. It's definitely not over processed like lots of M31s I see. Nice job mate

Who says you can’t image LRGB DSOs from a light polluted location?

Thats a great Andromeda Galaxy.👍

Thanks! I found the processing really tough. We're always learning and getting better though, so I'll keep the raw data and have another go in the future.

Haha, it's certainly possible! I'd love to do an experiment sometime, imaging from a proper dark sky site using all the same equipment. Bet I could match the quality in just a few hours, rather than the 24 needed here.

Me mate.  Many of them you can't and get washed out.  M31 is especially bright and photogenic.  Several others too such as M81 and M101 if is is overhead.  Narrowband is a different story of course.

You can image faint ones too. You need long integration times. The Iris Nebula is notoriously difficult, but here it is from Bortle 8, OSC, no light pollution filter.

I agree the core is bright but I think Lee has done a great job with the extended integration to get the fainter outer arms and the level of dust lane detail.
