My collegue Walter from Astronomy club Helios challenged me to rework my picture of M61 with Type 2 Supernova SN2020jfo. Walter edited the picture using Software Denoise Al. CS4 was used to approach this base as best as I can.
The result is the best so far. As described earlier, the picture is the result of two sessions, May 16 and May 20 with Nikon D7500 and TAL200K f/8.5 setting ISO 6400, 90x60s exposure.
