Supernova SN2020rcq
UGC 6930 (Uppsala General Catalogue of Galaxies) is part of the M109 group and located in constellation Ursa Major and about 50million ly away from Earth. The galaxy shows an "extra" star which is a supernova (SN2020rcq). The picture was taken with COAST C14 f/11 telescope on Tenerife. Exposure time 120 and no filters. I embedded a picture of UGC6930 from Simbad to compare with the Coast picture.
