Clear conditions last night in Sydney , arrived home a bit late and decided to capture a quick M20 again with the new ZWOASI2600MC camera
This time I pushed 3 minute subs using the 2” ZWO Duoband filter , Bortle 8 suburban skies , neighbours flood lights but no moon around

6” f6 Bintel newt on an EQ6-R Mount
ZWOASI2600MC with 2” ZWO Duoband filter and Baader coma corrector
Ascom camera control
Camera cooled to -10C
25 x 3 minute dithered guided subs
20 x darks
20 x flats
Goto and tracking EQMOD StellariumScope and Stellarium
Frame focus and capture APT
PHD2 guiding at 0.90 to 1.10 arc sec error total
Stacked in DSS
Processed in Startools V1.6 OSC linear data set RGB

Not one of my best Trifid’s to be honest

This time with 3 minute subs and just over an hour of data the noise was definitely more apparent under heavy light pollution than the last time I imaged this object but the Duoband filter did its job well . I have some options to look at following this result
More subs
Shorter subs
Cool the camera down to -15C to -20C
Cooler calibration frames
and so on ....
Although I am pleased with colours of the Outer star field, the reds
Stars ( orange ) stand out which is pleasing

Comments welcome
