IC 434 Horsehead South Coast
Despite the ongoing cloudy nights into the new year I managed a clear night last week at my NexDome Obs on the South Coast and imaged the Horsehead Nebula ( and nearby reflection nebula’s ) for only the second time.
Conditions were average with a northeaster blowing during the evening ( salty air , Im only 200m from the beach up on a hill )
8” f5 Bintel GSO newt
Skywatcher EQ6-R mount
ZWOASI2600MC set in Ascom to Highest Dynamic Range Gain 0, cooled to -10C
No filters ( only internal UV/ IR cut )
No moon
45 x 3 minute dithered guided subs
40 x Flats
50 x Bias
Goto and tracking EQMOD and Ascom Stellarium
Captured with APT
PHD2 guiding ( 0.70 to 0.80 arc sec )
Stacked in DSS
Processed in Startools V1.7 OSC linear data set
Unfortunately using a Newt on this target has its challenges with the larger stars like Alnitak and HIP 26549A projecting long diffraction spikes
I tried to reduce, colour tame and mask the spikes as best I could, still evident in the image.Still happy with the result for only a 2 hour capture.
