View Full Version here: : Chasing a fuzzy blob

Had a shot at doing the R Coronae Australis region recently and unsurprisingly discovered that I clearly need to work on my processing a bit more. Also noticed a fuzzy blob at the bottom of the frame. Got bored one night and decided to try and identify what I presumed was a distant galaxy. Ran Elbrus and located it at 19h01m17.56s, -37d37m41.3s then fed that position into Simbad and a few others but found nothing there. Took a closer look at it and realised that it had what appears to be a very fuzzy star in the middle so began to think it might be an early stage planetary nebula. Had a look at other images in the deep space forum and most people seem to process it either into a red star or process it out of existence. I'm beginning to think it's a dying red giant about to blow it's top off and become a full planetary nebula but that's just my wild guess. Does anyone know what it is??

I came to the conclusion it was a galaxy when I last photographed it. I don't have plate solving software but I did look up one incredibly deep photograph to help me reach that conclusion:

Its either PGC626897 or MGC-06-41-004
I can't get CdC to tell me which, but MGC-06-41-004 is more likely.

Managed to finally track it down. Had to get the exact co-ords using skyview first then feed that into simbad. Turn out there are four galaxies there!! The biggest one seems to be 6dFGS gJ190023.5-371224. Now there's an easy to remember galaxy number. Thanks for the effort guys. It's been an interesting and educating exercise finding a blob.
