Horsehead Nebula -
The Horsehead Nebula is just below the star Alnitak, the leftmost star in the belt of Orion, but is extremely difficult to see visually.
This image taken on 23rd January 2012 is the second image taken with my new CCD camera.
Exposure details: 16 x 10 minute guided exposures (= 2 hours 40 min total) through my William Optics Megrez 90 refractor at prime focus with an Atik 314L+ CCD camera. Bias and flat field frames also taken. A Baader 6nm Hydrogen Alpha filter was used as this region is rich in this wavelength and the filter is very effective as a light pollution filter.
