Supernova 2017eaw, discovered on May 14, 2017 by Patrick Wiggins in the aptly named "FireWorks Galaxy", NGC 6946. With 10 supernovas in the last century, it has been quite active in producing supernovas. Months later, near the end of August, the supernova is still quite bright. Revisited it on the nights of August 18-21 to capture this image of it with the RC10 and the Atik 314l+ camera.

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.
