This is an auto-guider with built-in dithering test shot. 45 mins of 3 min subs iso800 Canon 450D.
Processed in Asterism and StarTools. Slight touch up in ImageMagick.
This was point and shoot at a bright spot under an LED street light sky. No particular target and to my surprise it was centred on the nebula with some interesting clusters here and there.
Decided to take some bias and flats at iso100 and used dark frames from another recent project.
EDIT: I didn't get around to identifying the nebula's name - it's the Prawn... thanks Colin...
