Last night I decided that I'd try another idea for removing the tilt out of my Zeiss 135mm + QHY163M setup and although I didn't, I figured out where it is coming from. I'm thinking I need a guide scope ring to hold the camera as the 85mm rings I am using, although very stable, is the cause of the issue. The ring is the perfect size of the QHY163M but the Zeiss is a faction larger so the 85mm ring is pulling the camera down and causing the tilt.
I still need to get some proper calibration frames, so far I've just used everything I took overnight and stacked them together to remove the stars and give a reasonable dark, mostly to remove the amp glow. A makeshift dark.
NGC 6188 is a two panel with 3x300s per panel.
Paw + Lobster is a two panel with 3x300s per panel.
Prawn is a single panel 3x300s.
They're nothing spectacular and there is a stitch line but it does go to show just how much Ha is in these areas when you go into the super wide fields
