The image above comes from the average of ten, 300-seconds exposures, unfiltered, remotely taken with “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. SN 2019ehk is marked in the bottom right insert: it was discovered by Jaroslaw Grzegorzek and spectroscopy showed it to be a type II supernova. We estimated it as bright as mag. 16.0 (unfiltered, R-mags for the reference stars from the Gaia DR1 star catalogue).

Messier 100 was discovered by Pierre Méchain on 15 Mar. 1781 and it is a stunning spiral galaxy in the constellation of Coma Berenices. Located at about 55 millions of light years, it belongs to the Virgo Cluster. Several smaller galaxies are visible all around.

We plan to follow the evolution of this supernova, so stay tuned!
