    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

    W.O FLT110 with dedicated TMB field flattener
    FeatherTouch 3'' focuser
    Starizona MicroTouch autofocuser
    W.O ZS80 ED
    Meade DSI
    Filters: LRGB Baader Planetarium, IDAS LPS
    Sky-Watcher EQ6 Pro


    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
