NGC 3576 Statue of Liberty Nebula ( first image )
Clear night on Wednesday so decided to image the a Statue of Liberty Nebula for the first time. Moon was around 85% lighting up the whole sky
As the nebula was quickly decending in the South SW at sunset I only had less than 2 hours to capture it before being to low
8” f5 GSO newt
Skywatcher EQ6-R mount
ZWOASI2600MC set in Ascom Gain 100 Lowest Read Noise cooled to -10C
Optolong L Extreme filter
38 x 3 minute dithered guided subs
PHD2 Multistar guiding ( 0.65 arc sec error total )
Tracking and Goto EQMOD and Ascom Stellarium
Framed focused and captured with APT
Subs reviewed in Astap
Stacked in DSS
Processed in Startools V1.7 Compose Linear OSC Bi Colour ( Matrix )
SHO versions
Synthetic Luminance version
Obviously needed significantly more data on this object , preferably without the moon blasting across my OTA
This region has an immensely dense Star field so used the shrink module for dimming and Star size reduction plus a fair amount of noise caused by moon glare which had to be reduced
Happy to snag my first Statue of Liberty, can only improve on this effort
Comments welcome
Thanks
