Edit for New version:
Like most people posting here, I've been fighting with the weather for opportunities to get any data.
I've recently switched to Baader 36mm filters and this image is the first using them - only Ha (7nm) at this point. I can already see they're much better than the old filters I previously used.
The image has had a small crop to removed integration overlap issues, however sharp eyes will still see some less than ideal stars in some corners. I've got tilt in the system that I haven't been able to remove or work out a good solution for removing at this time.
I will probably reprocess this further as this was my first attempt at HDR Composition in PI. That core area is still intense and not quite right yet.

Sharpstar 107PH @ f3.9 (using 0.6 FR which is the culprit for amplifying the tilt issues) on G11 (actually, it's sitting on my RC10 on the mount).
ZWO ASI 1600MM-C @ -15C, 75 Gain, 13 Offset.
After weeding out the bad data, I used:
34 x 180 sec
34 x 120 sec
62 x 60 sec
130 x 30 sec
71 x 20 sec
72 x 15 sec
41 x 10 sec
Total: 20730 sec (5 hr 45 min 30 sec)
Taken from my heavily light polluted backyard in Brisbane. I actually tried to get some RGB data, but a mix of issues (weather, neighbour's competition winning Xmas lights display
and some technical errors) mean I'll have to start again on that. I am thinking of waiting until after the Xmas lights go - maybe new moon in Jan - to try again.
