Orion - M42 and B33
First processing attempt at data gathered for this target on 28th December 2016 from Surprise View car park in Derbyshire.
Base image
HA: QHY9, Baader 7nm filter, Nikkor ED180 @ f5.6 - 10 x1200s
RGB: QHY8L, SMC Takumar 200 @ f4 - 12x600s, 10x300s, 10x60s (HDR)
Ha added to red channel in blend mode lighten (PS) after star removal with Straton.
Detail
Horsehead and Orion nebulae shot from the same location with SW ED80 and focal reducer (510mm/f6.37) and QHY8L with approximately 1hr 20m exposure each.
All pre-processing in PI, master frames registered with Registar, post processing in PS and PI.
This is my first attempt using a dual rig and also shooting OSC with a non-ED lens. The red and blue channels were out of focus (no surprises there) and required extensive processing to remove the resulting red/blue halos around stars. This has resulted in the dreaded "panda eyes" which I have had a bit of a go at but are still present, needing more processing work or a mono camera with filters refocused for all channels :-). However, for now I'm quite pleased with the overall result, even if it doesn't stand up to being viewed at 100% or pixel peeping ;-)
Hope you like it and Happy New Year!
