Having read and seen much of this one on IIS, I've been keen to turn my scope on it and "have a look". On my 2nd night at the SPSP, for the last hour before astronomical twilight, I collected this data (while I froze my butt off
).
Pretty happy with the noise levels considering only 2 frames of each colour to stack. One thing I learned at Wiruna is the wisdom of collecting at least 3 (preferably 5) frames of every filter. Live and learn.
LRGB 25:10:10:10 (5min subs no binning)
QHY9/MPCC on 8 inch Newt
FOV approx 1x 0.75 degrees (approx 1 arcsec/pixel)
2 versions attached. Brighter one was my first initial "hack and slash" effort, which I'm now thinking may be a bit smoother on the eye? Edit: Both versions have had some of PixInsights "Dark Structure Enhancement" run over them to bring out a bit more of the ummm.... dark structure.
Comments/critique welcome please.
