Camera settings: RAW 8, 1304 X 976, Gain 350, Exposure 20.4 Seconds unguided, no darks, 103 Light Frames stacked in RegiStak (Deep Sky couldn't find enough alignment stars), processed in Photo Shop.
Forgot to add the M64 image was captured by my Meade LX200GPS, 10" at f/5 using an Anteres .5 reducer plus a ZWO IR blocking filter.
Same capture but re stacked with AS, with color intact.
