M42 Shorter exposures on a windy night
As my FOV is limited in Sydney only have reasonable views to the east and north ( 2 story neighbours houses, trees etc. you name it) and most objects are below 30 degrees most of the night so I imaged M42 again with a large number of shorter exposures
70 x 30 sec subs
15 x darks
15 x flats
ISO 800
Canon 600D
6” f6 newt
PHD2 guiding
Stacked in DSS
Processed in Startools
Very windy night gusts of up to 25 km/hr but guiding was running good considering at 1.5 to 1.8 total arc sec error with RA Osc around 3.2
Cheers
