My 2023 photo of the 21.000.000 LJ away Pinwheel Galaxy in the constellation Ursa Major – this year with supernova SN2023ixf.
50 Subs each 300s with my Vixen VC200L VISAC at 1800mm focal length on my HEQ5pro with my CANON EOS M100(a) in Koblenz, Germany.
Stacking and integration was done with PixInsight.
