Description

I managed to get a few nights imaging before the constellation disappears in the west, and with re-use of some old data from a year ago I got enough data to make a new version of the numerous nebulae located in the hunters right hip.
This is one of the most photographed objects in the skies, so one could think that it is imaged too much, but I never get tired of looking at images of this region because I seem to discover new things every time I look at images of the nebula complex.

Barnard 33, The Horsehead nebula. The nebula was actually discovered by Wilhelmina Fleming in 1888 and named by Edward Emerson Barnard who described, it as "Dark mass, diam. 4′, on nebulous strip extending south from ζ Orionis", (Wikipedia) and catalogued the nebula as B33.
The nebula is a part oft the much larger region LDN1630. (LDN: Lynds catalogue of Dark Nebula, published in 1962)
