Sadr (Gamma Cygni) and the surrounding nebula
Camera: Sony A6400 (no mod),
Lens: Samyang 135mm f/2,
Mount: Skywatcher HEQ5,
Sky: Bortle 5, no moon.
Around 400 of 30 s subs pre-processed, stacked and post-processed in Siril with a pretty standard procedure. However due to moderate light pollution quadratic background extraction was applied already at sub level. Shot at f/2.8, ISO 400.
Visible near the upper right corner is the Crescent Nebula (NGC 6888). The halo around Sadr is a result of lens optics and I did not attempt to remove it. A reflection nebula near the lower left corner around 44 Cygni is also visible.
