DG 19 LRGB


DG 19   LRGB

DG 19, also known as LBN 721 or vdB 18, is a very faint reflection nebula located around the HIP 16724 (http://simbad.u-stra...16724&NbIdent=1). This is the blue, magnitude 7.65 star at the left of center in my image. There’s barely a hint of the blue nebulosity. Lynds’ rates this one as a 5 (where 6 is the dimmest). The rest of the dust in the area is cataloged as LBN 718 (below center) and LBN 719 and 720 (on the right edge). The dust-obscured open cluster at the bottom right is NGC 1342.

Luminance – 12x600s – 120 minutes – binned 1x1
RGB – 7:6:6x300s – 35:30:30 minutes each – binned 2x2

215 minutes total exposure – 3 hours 35 minutes

Imaged February 26th and March 20th, 2014 at the Danville Conservation Area (New Florence, Missouri) with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm. The RGB was imaged through high, thin clouds.
