About this image

Galaxy M100 showing supernova sn2020oi just north of the core. This is an unprocessed "raw" image so it should be possible to determine the magnitude of the supernova. The magnitudes of two comparison stars are noted (magnitudes from SkyMap Pro 10) The simple magnitude tool in Maxim is fooled by the bright core but the closest I can get is about magnitude 13.4. Raw FITS file available to anyone who knows how to do proper photometry :-)
