Image Details:

Upon hearing about the new supernova discovery by Koichi Itagaki, I did what every budding astrophotographer would do: I rushed outside with my telescope and camera on the first clear night we had! This image is a comparison of M101, the Pinwheel Galaxy, taken roughly one year apart. The original image on the right from April 24th, 2022, and the current image on the left, taken last night, May 21st, 2023, to show the appearance and location of the type II supernova discovered in the outer arm of the galaxy a few days ago (and also a bit of growth in processing/capture skills). It is already expanding in size and brightness very rapidly, and is certainly somewhat of a rarity to be able to witness in such a dynamic state. It can be seen in the left image as the bright blue/white star-like appearing object.
