About this image

The latest monthly image of this fascinating nebula.  Subtle changes since my last image on 6th October so at least when I update the animation it won't be too boring...

Field is ~ 15 x 15 arc minutes with north up and shown at 150% original size. (36 images from 25th October were combined with 160 images from 28th October)

Location of nebula:  RA 20:45:56, Dec. +67:57:44.

Update 1st November:  Original image replaced with latest version which incorporates more images from 30th October.  Now a total of 354 x 30 seconds, i.e. almost 3 hours imaging time.
