Description

Decided to process some crappy data I captured 2 weeks  ago on M16 Eagle Nebula from my City Suburban residence. 

Bortle 8 Skies
New Moon 
Sky Conditions : Average to Poor seeing 
Telescope: 8” f5 Klaus Helmerich Carbon fibre Newt
Imaging Camera: ZWO2600MC cooled to -10C , Gain 100
TS Optics GPU coma corrector 
Filter: Antlia ALPT 5nm Dualband filter
Guide Scope: Orion 60mm with helical focuser 
Guide camera: ZWO120MM-S
92 x 2 min dithered subs 
20 x Flats
20 x Bias
EQMOD and Stellarium 
APT
PHD2 Multistar guiding ( 0.50 to 0.60 arc sec total )
Subs reviewed in ASTAP
Stacked in Deep Sky Stacker
Post processed in Startools v1.8 Dats set loaded via Compose , used OSC Bicolor luminance , Color option 
Initial Autostretch was quite noisy but managed to mitigate the gradients and settle on a reduced dynamic range to clean up the image a bit. Included a default SV Decon and applied Superstructure ( brightness) 
Color preset was an SHO preset with saturation and bias adjustments 

Comments welcome 
Thanks for looking
