Shown above is supernova SN2022hrs taken with my Hyperstar4 on the night of April 21-22, 2022, at the New Forest Observatory in southern England. Clear, moonless nights in England are quite rare, so it was a treat to not only have such a transparent night but to be able to observe a supernova to boot. This supernova was discovered by Koichi Itagi on April 16, 2022, just a week before I was able to observe it.

SN2022hrs is found in the spiral galaxy NGC4647, some 63 million light years away. It's almost overshadowed here by the massive elliptical galaxy, M60 to its lower left. M60 and NGC4647 are part of the Virgo supercluster of galaxies and lie close to the well-known grouping called Markarian's Chain.

Photo details: Imaged with an ASI 2600MC-Pro colour CMOS camera (26 Megapixels!!) on a Hyperstar 4 lens connected to a wedge-mounted Celestron C11 GPS Schmidt-Cassegrain reflector. The image is only 16 x 3-minute subs (exposures). It was captured from 23:00 (local time) on the night of the 21st until 00:40 (local time) on the morning of the 22nd.
