Ceres meets Galaxy

Image Description and Details : The Dwarf Planet or Asteroid CERES crossed my field of view of the galaxy M100 in constellation coma berenices from 24th to 29th of March 2023, imaging from Augsburg (Germany) with the private remote scope "Wolfatorium" in Hakos, Namibia. To document this "transit", short images where taken at 21.00 and 1.00 CET every day. Additional images were taken at 4.30 on the night of crossing the galaxy. The whole field was imaged with much longer exposures for two nights before CERES entered the frame. The Asteroid images were made starless and the single - strong dimmed - CERES copied into the galaxy frame.
