Hello this is my first image after having tuned my 12" RC
Capture info: TPO RC 12" - MI250 - Atik 383 - Astrondon 5nm filters
Ha 5h, OIII 4,5 h SII 8h
Maxim DL-ACP for capture, PixInsight for processing
~0,53 arcsec/pixel
I used no flattener (have none for this telescope) but I think don't need one until I use a larger chip.
I almost doubled the expo on SII because I found it very noisy.
Small picture looses a lot so here half res picture

I'm not very sure/confortable with the processing, so comments welcome.
Geert
