Taming Sadr with a Samyang 135 and ASI183

[Adreneline]

This image is nothing much to write home about but I was keen to revisit Sadr and try to get a result where Sadr itself does not dominate this region of nebulosity.

This image is just 12 x 300s of S, H and O taken in nautical darkness and no Moon, taken on 23rd May.

Pre-processed in APP and post-processed entirely in PixInsight:

Presented at 1:1 with only minimal edge cropping so you can see the star shapes all the way to the edge:

I am pleased that even with the Samyang 135 mm I have been able to reveal the beautiful area of nebulosity at the centre of Sh2-108 that is so often obscured by Sadr itself, a star that is well separated from the Gamma Cygni nebula and plays no part in ionising the nebula.

Solved to reveal the main features:

Even in grey scale it presents well:

Thanks for looking.
