LBN 683   LRGB

Lynds’ Bright Nebula 683 is a large (around 3 degrees) cloud located in Ursa Major. Lynds’ scale of brightness puts this one at a 6 with 6 being the faintest. This image is centered on RA 09h 16m 02.4s, Dec +70° 45' 05.6". When searching for more information, I couldn’t find any images so this might be the first color image.

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

240 minutes total exposure – 4 hours

Imaged January 29th and February 26th, 2014 at the Danville Conservation Area (New Florence, Missouri) with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.

This is another one of the odd choices of objects that can be found in the Astronomy League’s Bright Nebula Program.
