NGC 2175 and Sh2-252, the "Monkey head nebula"

A blog post about this object with more info and images.

NGC 2175, it's surraunded by an emission nebula Sh2-252, it's sometimes called as a "Monkey head nebula". NGC 2175 locates in constellation Orion. In my northern location, 65N, this target is not very high, about 39 degrees in maximum elevation. Distance from Oulu, Finland, is about 6350 light years.

Technical details:

Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.

Optics, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO, an active optics unit, and Lodestar guide camera 8Hz
Image Scale, ~0,8 arc-seconds/pixel
12 x 1200s exposures for the H-alpha, emission of ionized Hydrogen = 4h

Optics and exposures used for colors

Tokina AT-X 300mm at f2.8
QHY8, a cooled single shot color camera
Baader UHC-s filter
Baader IR-cut filter
22x600s = 3,6h
