The Swan Nebula M17

Description

This is the result of LRGB captured in the past week using the 12" Ritchey-Chrétien combined with H-Alpha data captured last year using the 3.6" TMB92SS refractor.

The latest data was all binned 2x2 (including the luminance) as my image scale is still a very reasonable image scale at just under 1 arcsec/pix

Total integration time 7 hours
