Horsehead Nebula

The Horsehead Nebula (B33), captured with a new camera (ZWO ASI071MC Pro), through an AstroTech AT8IN telescope at f/4. It was a moonless night with better than average transparency and average seeing. A Baader MPCC Mark III coma corrector and a Baader UV/IR blocking filter were employed. The camera's sensor was cooled to -10 degrees Centigrade. At this temperature the environment was condensing, so the camera's built-in anti-dew heater was employed.

120 exposures of 45 seconds each were acquired with SharpCap software. All image processing was performed with PixInsight.
