Description

At 53°N, nights are very short now, therefore, for an LRGB sequence of M 101 with the Supernova SN 2023ixf, I had roughly only 1.5 hours. The moon was at first quarter, which additionally brightened the sky. Considering this, I was quite happy with the final result. It seems that the reported blue color of the Supernova has changed to a bluish white, comparable to the color of Vega. I did not make colorimetric measurements though.
