Description

This image is the sum of 1154 60 secs unguided subs taken during the nights of the 28th, 29th and 30th of august from my home terrace. Newton Orion 250 f 3.9 Telescope, qhy183m cooled camera, on top of an Ioptron CEM60EC. Aquisition with Astroart. Processing with PS.

The Ghost Nebula (designated Sh2-136, VdB 141) is a reflection nebula located in the constellation Cepheus.

It lies near the cluster NGC 7023. Looking at the adjacent image, the nebula's name is easily understood. The Ghost nebula is referred to as a globule (cataloged CB230) and over 2 light-years across. There are several stars embedded, whose emissions make the nebula shine in brownish colour. (Wikipedia)

Thanks for looking
