This was taken over 2 years. Its really a dark site target as its very faint and only really shows up in O111. So a 3nm O111 filter would have been handy here.
This is 14 hours and 29 minutes of O111, Ha, LRGB. Even so there is some residual noise. A bit of tilt hadn't been corrected at this stage so there is a little bit if you look for it.
FLI Proline 16803, AP Honders Riccardi 305mm F3.8.
I was amazed by the photos I had seen of this object. There aren't many images of it I guess because it is so faint. I wanted to image this object for quite a while now. It was also extremely hard to process. I had several goes at it and would hit a dead end and I would leave it to come back to later. Today I managed to get an image I liked.
Taken from my home observatory.
