Thanks Marc. Ah... I wish it was easy! The ever increasing light glow from Sydney makes my urban imaging more difficult with time. I've also much more work to do due the fact I'm now using an instrument rotator.
Fantastic for acquiring bright guide stars, but now I need flats for each unique camera rotation angle.
While I prefer sky flats, I suspect I'll need to migrate to a softly glowing El panel soon (sigh...more expense! ) for timely calibration frames. If you push my recent effort (above) to the nth degree, you'll see radial illumination background changes, which simply are due the flat fields being a few degrees off....More exposure time would good, plus a larger scope, larger dome, better seeing....
