An excellent week and weekend for astrophotography. I spent all week watching the sun during the day, and both friday and saturday night had clear skies and moonrise at about 4am. I spent the early hours of friday night (march 13th) capturing RGB-data for the Rosette Nebula. When the Rosette Nebula disappeared below the horizon, I turned my telescope to the Leo Triplet (M66 group), and managed to capture about 4hrs of good data before I had to get some sleep. The result was the LRGB-image of the Leo Triplet:
