RA 03:46:01.80 Dec 23:51:43.0
4 x R 180 sec bin 1
4 x G 180 sec bin 1
4 x B 180 sec bin 1
Debloomed, calibrated + 2 x Filter DDP, then combined & RGB stacked in Maxim. A little photoshop to get a pleasing colour balance.
What intrigues me is this (below) object, a faint fuzzy purple blob that seems to be in all my subs, but I can find nothing in other images on the web.
.....In fact, even while writing this I may have discovered the cause. Rotate the image 180 degrees and superimpose on the original and it coincides perfectly with the star Merope. Either some sort of internal reflection, or possibly a ghost from my images taken prior to the flip as the scope passed the meridian
