Got an extra hour of colour data so have added that to the mix with some happier results. Details are: f7.5 ED80 on a recently belt modded HEQ5, ZWO ASI1600MM-Pro with EFW, Ha (5nm) 130 mins (28x 300s), RGB 49 mins each (49x 60s), captured in Sequence Generator Pro, calibrated and aligned/combined in Nebulosity and processed in StarTools. Really appreciate advice. My colours always tend to be a bit garish but I liked what naturally fell my way with this one (not so much by design).
Astrobin so you can see the noise!
