Field of view 39 x 27 arc minutes with north up. Location of nebula: RA 20h 46m  Dec +67d 58m.

Monthly image of this variable nebula as part of the BAA variable nebula program.  Currently the nebula is in a relatively stable phase showing little if any change over the last few months.

The best images from a 4 hour observing run were combined to extract as much nebulosity as possible on a very damp night. At the end of the nights imaging, at 4.30 am, the condensation on the top of the telescope had frozen solid!
