Hi everyone,
Early last week spent 3 nights shooting M17 from near Heathcote, Victoria, Australia under dark skies. There was frost on the scope on one night.
Taken with a 10" CDK scope, AP900 mount and 1600mm camera.
Approximately 4.5 hours of Luminance, with 3.25 hours of RGB data, all 3 minute exposures. The core and surrounding areas also has some Ha blended data I took last year from severally light polluted Melbourne with a 4.5nm Ha filter.
Was hoping to get more of the extended nebulosity, but would say I need to get more Lum hours up on this object to achieve this.
Used Pixinsight and the ArcStretch and HSV Star Repair Script to maintain the core star colours.

Clear skies,
