    Messier 100

    Not so popular Messier object M 100 is a bright member of Virgo Cluster 55 million light years away from Earth with diameter 2/3 of Milky Way.
    Processed in PixInsight and finetuned in Photoshop.

    For getting best SNR and resolution, sum of 50% of best FWHM subframes were processed separately and later combined with all other subframes by mask to get super luminosity channel for LRGB. Stretched using Arcsinh process.
