"Image is of SH2-124, a rarely photographed emission nebula in Cygnus thought to be 8,500 ly away.

The image is 4 1/2 hours of Ha through a 3.5nm Baader NB filter using an Atik 460e /Mak-Newtonian 190/Maxim/Dss/PS5.

The B&W image shows good detail so I abandoned introducing colour as both the O3 and S2 (after 2 hours each) were too weak to effectively use.
