Hi Gary
Thanks for your research, your resources are richer than mine.
I managed to get out again tonight and take another LRGB set of 120:60:60:60 Frames at 30 secs each and I have just punched them through PixInsight.
My post processing skills are still a little basic so I'm not getting the best out of the data. Also, as I set up and tear down each night, I've been a little sloppy in camera field orientation, so I have just ringed the PN in Red and the faint fuzzy in Yellow just to identify them.
I can just make out 2 point-like concentrations in the fuzzy blob in the Raw PSD File, so I hope they make their way into the JPG.
Bed time for me now.
Cheers
Dennis
