About this object

This image of M33 is a reprocessed image. The Luminance, Red, Green and Blue frames were originally taken in Aug of 09 with a Stellarvue SV115T refractor and STL 11K CCD camera. In Dec of 2010, I took the Hydrogen Alpha exposures through a SV80ST2 refractor, QSI 583 camera and Astrodon 3nm Ha filter. The image is a composite showing both the blue star forming regions and reddish Hydrogen Alpha nebula regions which abound in M33. The image on the right is the processed Hydrogen Alpha image which was continuum subtracted showing only the nebulous regions within M33.
