Barnard 157 + 365 + Sharpless 127

Barnard 364 pretty much consists of all of the dark nebulae in the image including Barnard 157, the circular smudge just above center.

Sharpless 127 (LBN 436 and others) is a faint red nebula near the center on the left (east) side of the image.

I found that I imaged this one a second time so I decided to combine the data.

Luminance – 48x600s – 480 minutes – binned 1x1
RGB – 16x300s – 80 minutes each – binned 2x2

720 minutes total exposure – 12 hours

Imaged from Dardenne Prairie, Missouri (a red zone) on September 4th and 12th, 2018 and August 4th and 6th, 2019 with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.
