About this image

Latest image of Gyulbudaghian's variable nebula shows the continued, slow development of the NE pointing nebula. Actually got it in focus this time(!) so it's a bit sharper than my previous image at F/3.6 from 17th April.  The image from 23rd April, at F/6.8, shows similar detail but doesn't go as deep so the northern most extension isn't recorded...or maybe it wasn't there?

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