Supernova 2023ixf in M101

I'm sure many of you may already know of the supernova that occurred in the Pinwheel galaxy, M101. I wanted to capture it as soon as I could but, as usual, clouds prevented me from doing so until May 26, when it cleared sufficiently to get a decent image.

I had taken an image of M101 way back on Dec 28, 2013, when I was just starting out with astrophotography. I had recently acquired my large telescope (the EdgeHD11) and this was one of my first attempts at imaging a galaxy. I didn't even own a dedicated astro camera back then - the image was taken with my Canon 50D body. I'm not sure why I haven't taken a recent image of M101 as it is a wonderful galaxy, but that's another story.

Amateur astronomer Koichi Itagaki discovered it on May 19, 2023. The supernova should remain visible to amateur astronomers with backyard telescopes for a few months. The supernova – named 2023ixf – lies in the direction of the constellation Ursa Major, near the end of the handle of the Big Dipper.

So here is my image of M101 with the supernova marked (and the 2013 image for reference).
