M17 Omega Nebula False Color Hybrid

Description

I was going to present this using the CFHT palette but it looked horrid so instead I did a false/natural color version with H-Alpha assigned to Red, SII assigned to Green and OIII assigned to Blue. I'm far from happy with the stars but maybe next year I can capture this target in broadband

Captured over 3 nights early October 2012 shot at native resolution (F5.5)

Total Exposure time 5 hours.

Location: Fremont, Michigan

Date of Shoot 1st, 3rd and 8th October 2012

All exposures unbinned

H-Alpha 3nm 8 x 20 min

SII 4 x 20 min

OIII 3 x 20 min
