This image of Crab Nebula was taken at the end of 2009.
The image is made by a RGB acquisition with a unmodified Canon EOS 450d and a RNT24" by me and a Ha sequence with a MZ2-Pro CCD by Davide Manca.
Both RGB sequence and Ha sequence are 2 hours long.
The Ha sequence has been added to RGB image boosting details and color of the nebula
Star have been masked for enhance nebula vision.
