[dcrowson]

Sharpless 303 (Bran 3, LBN 1047 and others) is a faint HII region located approximately 1700 light-years away in Canis Major.

There are a lot of other designated nebulae and dusty regions in this image. Several denser areas can also be found in the Planck Galactic Cold Clump (PGCC) catalog.

Luminance – 12x600s – 120 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2

240 minutes total exposure – 4 hours

Imaged on January 12th, 2021 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.

This object would be brighter in Ha but my limited time prevented capturing data.
