Had a few nights away in the Flinders Ranges in SA and clear skies allowed for a few objects. Some still to process. But attached are two images with only luminance taken at the dark sky site and colourised with data from previous images I've taken in the suburbs of Adelaide.
Trifid is about 2.3 hours of luminance (and 10 hours of colour from a suburban OSC image).
Corona Australis is about 5.5 hours luminance (and 2.25 hours of RGB data from the 'burbs).
The idea was to try to improve the previous suburban images with more detail in the Trifid (using a ZWO ASI 1600 now instead of a QHY8) and less noise in the dust lanes in Corona Australis due to the dark sky. But the seeing could've been a bit better though to get more detail I think.
Scope is an RC8 on a Mach1 mount (new and now superceded already!! :doh:).
