LBN 754 is the brightest HII region in the top left of the image. Some of the other nebulosity is cataloged as LBN 755.

Barnard 25 (LDN 1465 and others) is the dark nebula near the bottom right.

This whole field is somewhat obscured with dust cataloged in the Planck Galactic Cold Clump (PGCC) catalog - I have a feeling that the combination of the IFN and HII could have led to the somewhat odd colors.

Ha – 26x1800s – 780 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

900 minutes total exposure – 15 hours

Imaged from Dardenne Prairie, Missouri (a red zone) on December 22nd, 2021 and January 3rd, 9th and 10th, 2022 with a SBIG ST-8300M on an Astro-Tech AT90DT at f/6.7 603mm.
