Description

Lynds Bright Nebula 438; Lacerta

Astro Systeme Austria N12 f/3.5 astrograph

KAI-11000M; SBIG STL

Total Exposure Time: 8 hours; LRGB 260:80:60:80 minutes, unbinned

July 2008; Inkom, ID

Comments: This dusty region in the summer sky is rarely imaged. This is a beautiful example of galactic dark nebulae at high latitudes that become visible through illumination by the interstellar radiation field this is known as Extended Red Emission (ERE). ERE is a dust-luminescence process, which appears in a broad band extending in wavelength across the R-band. ERE also often appears in narrow filaments on the edges of clouds and may therefore be mistaken for H-alpha emission. This nebula emits no significant H-alpha signal. It's shape reminds of a cometary globule in its very last phase before being dispersed (Schedler).
