M20 Trifid Nebula
Captured M20 on Sunday night in Sydney with good conditions until just before midnight.
Haven’t imaged this target in Sydney for at least 18 months or longer
It’s a unique little target with emission, reflection and dark nebula and an interesting Star field
Bortle 7/8
No moon
No dew ( until midnight )
6” f6 Bi tel GSO Newt
EQ6-R pro mount
ZWOASI2600MC cooled to -10C , Gain 100 LRN
No filter ( only inbuilt UV/IR cut )
TS GPU coma corrector
52 x 90sec dithered guided subs
40 x Flats
50 x Bias
EQMOD, Stellarium and APT
PHD2 Multistar guiding ( 0.60 arc sec error total )
Stacked in DSS
Processed in Startools V1.7 OSC linear data set
I use the Entropy module which dampened the brightness a bit , should have used Super structure module , isolate or brightness
Comments welcome
Thanks
