      Description

      The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, the M66, and the NGC 3628

      Instruments and exposure data

      Lum(LPS):30*10min(bin1x1)_51*10min(bin1x1)
      Red:36*5(18bin1x1_18bin2x2)
      Green:36*5(18bin1x1_18bin2x2)
      Blue:44*5(24bin1x1_20bin2x2)

      Total exposure time:23h10min

      The data taken during 5 nights from 25/3/2011 until 24/4/2011
      Some blue and luminance data was forgotten so i try a complete rework
      I try also a selective LR deconvolution with CCDStack 2 and Registax wavelet.

      ''Variable Background Flatten'' with the free ''Fitswork'' Software is highly recommended
