About this image

Probably unwise to shoot a broadband target with the Moon being quite bright but thought I'd give it a go. Even with almost 4 hours of data this is probably one to return to when full astronomical darkness returns.

That's a really nice image Callum.  I see you've also captured Gyulbudaghian's nebula at the right of the frame.  Shows how small it is! I'm certainly interested to see what you get in a dark sky...

Thanks Mike for the compliment and for pointing it out.  I hadn't spotted it and had to go back to the raw data to check it wasn't an artefact of the processing but it is indeed there.  Hoping to be under Bortle 4 skies in a couple of weeks.  If its clear I'll grab some more data.
