Gee I wasn’t expecting an APOD with only 7.5 hrs of data on a dim galaxy.
If I captured 15 to 20 hours plus then things would be entirely different.
Ok all points of critique understood and accepted.
I’m going to revisit the processing and boost the brightness at the expense of loosing some fine detail , plus boost saturation to bring out more colour.
As far as the stars are concerned, I didn’t use the fringe killer tool , highlight repair or colour taming tool in ST to correct the colour aberration, my fault !!
Admittedly I held back on the auto stretch to mitigate some fine noise ( I did have some moon glare on 30% of my data over both nights )
5 min subs in lieu of 3 min would have improved detail. I did try stacking in both DSS and ASTAP and ASTAP was the clear winner with a clean lower noise image.
At the end of the day more good data would improve the image quality , no doubt about that.
As I normally image in B8 skies in Sydney , imaging under B3 at my Dome on the South Coast on a broadband target is an ongoing WIP and experimentation.
My imaging time over a calendar year is usually 70/30 ( Sydney / South Coast )
Broadband imaging in Sydney is virtually impossible due to the amount LP under B8 and the availability of clear sky time during new moon periods.
Thanks all for your input
Cheers
Martin
