Continuing cloudy nights on the east coast are becoming the norm lately so when a window of opportunity presents itself you get a bit excited and hope you can squeeze in a few hours of imaging
Yesterday arvo and last night was looking good , until the cloud rolled in again around 10pm ( was suppose to be clear until midnight)
Managed only 20 minutes or so on the Tarantula which I’ve only imaged once in the past year
Conditions were not too good , salty nor easter , 88% humidity and 50% waxing moon overhead ( you take what you can get )
Due to the limited data, stretched image had a higher than normal noise floor but Startools did a good job of mitigating most of the gradient and noise mottle
NexDome Obs
8” f5 GSO Bintel newt
EQ6-R mount
ZWOASI2600MC set in Ascom to highest dynamic range Gain 0 , cooled to -10C
Baader MCCP Mk3 coma corrector
8 x 3 minute dithered guided subs
No Flats
No Bias
Goto and tracking EQMOD and Ascom Stellarium
Framed focused and captured with APT
PHD2 Multistar guiding ( 0.75 to 0.85 )
Subs reviewed in Astap
Stacked in DSS ( Average )
Processed in Startools V1.7 OSC Narrowband Bi Color ( Compose module )
In Colour module used the Matrix
SHO versions
