About this image

This Supernova known as SN 2022hrs was discovered recently by an amateur astronomer Mr Koichi Itagaki on 16^th April this year. It is in a spiral galaxy known as NGC4647, which is about 63 million light years from us, the supernova is brighter than its host galaxy.

Integration time was 5hrs 20mins. Captured between 4^th to 8^th May22.

It’s the first time I have imaged a supernova that is at the bring of its life. This one has special meaning for me – it was discovered exactly 2 years to the day after my father suddenly passed away. I’m a pragmatic scientist and not given to flights of fancy but I do feel closer to dad just by imaging this target and making sure I now have an image of a bright spark in the universe that was found exactly two years after his light on Earth went out…..

Processing; Deep sky stacker, PixInsight with final tweaks in Photoshop + Topaz DeNoise

Clear skies all.

Excellent! That's a lot of exposure and it clearly paid off. A lovely story behind it too - no doubt your dad would be proud.
