The Swan Nebula/Omega Nebula (M17) in Narrowband


The subs exposed for this image were done almost a year ago and I completely forgot about them.

This image consists of a total of 16.5 hours exposure time on SII, HAlpha and OIII data over multiple nights of imaging.

Imaged through a BOSMA 80mm refractor at 500mm focal length (f6.25) using a full spectrum modded Canon 40D DSLR.
