A Quick M20 Trifid Nebula
Captured M20 Trifid Nebula a week ago on a night with average seeing and passing cloud
Managed to gather 18 x 3 minute reasonable subs with my 2600MC ( no filter ) discarded about a dozen subs
NexDome Obs
8” f5 GSO newt
Skywatcher EQ6-R pro mount
ZWOASI2600MC set in Ascom to highest dynamic range Gain 0 , cooled to -10C
No filter
Goto and tracking EQMOD and Ascom Stellarium
Framed focused and captured with APT
PHD2 Multistar guiding ( 1.00 to 1.20 are sec error total) poor seeing
Stacked in DSS
Processed in Startools V1.7 OSC Linear data set
I’d like to capture M20 again on a better night with more data
It’s a great little target with emission , reflection and dark nebula plus an interesting star field
Comments welcome
Thanks
