M33 1/2/11 Remix

21 January 2011

During the brief period of clear nights in early January, I took the opportunity to get additional exposures of M33 to improve the image detail.  The following image is the combination of data from 11/04/10, 12/31/10 and 1/3/11.  This represents an amazing total of five hours and 50 minutes of exposure time!  The result is one of the most detailed amateur photos of M33 I have seen.
