Ive been abroad for a few months, just returned home , and with a couple of clear nights in Sydney, decided to dust off the rig and image M17.

Full Moon
Bortle 8
Sky Conditions , poor seeing
8” f5 Klaus Helmerich Carbon fibre Newt
Skywatcher EQ6-R pro mount
ZWO 2600MC cooled to -10C , Gain 101
Antlia ALPT 5nm Dualband filter
TS Optics GPU coma corrector
PHD2 Multistar guiding ( 0.75 to 1.0 arc sec ) guiding was poor due to conditions and seeing

95 x 3min dithered subs
40 x Flats
60 x Bias

Stacked in DSS
Processed in Startools v1.8
AutoDev, Bin 70% , Crop edges, NB Wipe , Final AutoDev, Sharpen, SV Decon , Superstructure, Noise reduction
Had to deal with a lot of gradients even with using the Antlia filter but ultimately using a OSC it alway gets back to how data you can capture, the more the better. Under Bortle 8 and full moon staring down the end of the OTA a OSC needs loads of good data to produce a reasonable low noise high fidelity image. This image fell way short ( the clouds have returned ) Maybe in a week or two I can add more data under darker moonless skies.

Synthetic Luminance version
Synthetic Luminance Crop version
Colour version SHO mapping

Comments welcome

Thanks
