First Light NGC 6357 Lobster Nebula
Posted: Thu Jun 09, 2022 2:17 am
First image of NGC 6357 Lobster Nebula under Southern Hemisphere skies
City suburban Bortle 8 Skies
20% waxing moon
6” f6 GSO Newt
ZWOASI2600MC cooled to -10C , Gain 100 LRN
Optolong L Extreme filter
TS GPU coma corrector
245 x 2 min dithered guided subs ( captured over 3 nights )
40 x Flats
60 x Bias
EQMOD, Stellarium, APT
PHD2 Multistar guiding ( 0.55 to 0.60 arc sec total)
Stacked in DSS
Processed in Startools V1.7 Compose OSC Bi Color
SHO version using the 4th Matrix option
Battled with a lot of LP gradient due to location but cleaned it up as best as I could, obviously sacrificing some faint detail
Comments welcome
Thanks
