    Description

    a closeup of the Leo triplet, using my Lacerta 10" f/4 Photonewton and ZWO ASI1600MMPro (gen.1, gain zero) and Astronomik Deepsky LRGB filters. The sharpest L frames were selected and stacked separately for the highlight details, while (almost) all frames were used to get the weak signal and best background.
