Description

M100 and many other distant galaxies of Virgo´s Cluster shot on night 18.03.2012.
Flat image didn´t work as I expect and I had to use gradienxterminator to correct background. Guiding works pretty well and I got 5min sub exposures consistently.
Weather was one of best of the season 2012.
