NGC 3631 is a face on spiral galaxy located in the constellation of Ursa Major. Located some 50 million light years away, on March 13, Ron Arbour discovered a supernova in this galaxy. Currently around magnitude 15, it is easily visible in the galaxy. It was determined that this was a type 1b supernova, which is a massive star that underwent a core collapse. These are often Wolf-Rayet stars that have blown off most of their outer layers of hydrogen.
Imaged with the ED80CFT refractor, and Atik 314L+ mono ccd, it consists of 9 x 300 second images through R/G/B filters, and 39 x 300 second luminance images.

My attempt at NGC 3184, a spiral galaxy located in the constellation of Ursa Major, and home to a recently discovered supernova SN 2016bkv by Koichi Itagaki on March 21, 2016. Currently at magnitude 15, and located at a distance of 25-55 million light years away for the galaxy, we are seeing an event that happened long ago.
Taken with an ED80CFT 80 mm refractor with an Atik 314l+ mono ccd. Exposures of 300 seconds through L/R/G/B filters.
