the cyclone season has started

Here's a LRGB composite of NGC 2997 from my backyard in Perth, with the trusty 10" starfinder, QSI683wsg on a G11. Processing in pixinsight.
Had some real problems with the calibrations - maybe it's the light pollution but I acquired 3 sets of flats at dusk, and none of them worked very well.
Subs are 5 minutes each, and I got 16 each for the colour channels and 32 for luminance.

cheers, and thanks for looking.
Andrew.
