The Rosette Nebula - C49

The Rosette Nebula is just to the East of Orion, but is extremely difficult to see visually. The open cluster of stars in the centre (Caldwell 50) is readily visible and is used to check that the telescope with camera are pointing in the correct place.


This image taken in January 2012 is the first image taken with my new CCD camera.

Exposure details: 26 x 10 minute guided exposures (= 4 hours 20 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 7nm Hydrogen Alpha filter was used as this region is rich in this wavelength and the filter is very effective as a light pollution filter.
