Gyulbudaghian's variable nebula

Ipswich, UK

First opportunity to image Gyulbudaghian's nebula from home since it faded from view a few weeks ago. The image has been highly stretched, so is rather grainy, but only the background nebulosity of the giant molecular cloud remains.

Can be compared to my previous remote image of 8th October and home image on 18th September.

Location of nebula, RA 20h 46m Dec +67 58, field of view in image is 15 x 15 arc minutes with north up. Reproduced at 150% of original size.
