Description

This is a quick, one night, narrowband (SHO) image of M17 the Omega Nebula (aka the Swan Nebula) in Sagittarius. Camera was the ASI1600MM-C, running at -25C. Taken with a gain setting of 139. as the target is such a bright object, sub times were reduced to prevent blow-out. Subs consisted of: 24x120s Ha, 12x120s Oiii, and 24x120s Sii. Processed in DSS and Photoshop CC.

There appears to be a little sensor tilt evident in the upper left, or maybe the reducer/corrector was not spaced properly.

Scope was a TS Photoline 115mm APO, reduced to f5 for this sequence. Mount is the CGX.
