M17 Omega (Swan) Nebula under Full Moon
Posted: Tue Aug 01, 2023 7:51 am
It’s been quite a few months since I last imaged ( my Wife and I eventually travelled abroad to UK and Malta after COVID put a stop to our plans in 2019 )
Dusted off the rig and imaged M17 under a near full moon with less than ideal conditions ( guiding was atrocious) Heavy dew arrived early into the evening.
Bortle 8 City suburban skies
95% waxing moon
8”f5 Klaus Helmerich Carbon fibre Newt
EQ6-R pro mount
2600MC cooled to -10C , Gain 101
95 x 3 min dithered subs
40 x Flats
60 x Bias
EQMOD and Ascom Stellarium
APT
PHD2 Multistar guiding ( 0.75 to 1.0 arc sec total )
Stacked in DSS
Startools V1.8 Compose OSC Bi Color
Used the 4th SHO mapping in color matrix
Gradients were quite severe which restricted exposing more detail (post Wipe) during final AutoDev
Applied a default ( 10x iterations ) SV Decon with 16 Samples to deblur main structure with resultant white point stars.

Attached SHO image and also a Synthetic Luminance version for finer detail
Thanks for looking
Comments welcome
