Here’s a couple of recent supernova images. The first is a color image of supernova 2014G in the host galaxy NGC 3448.
The supernova 2014J is located in the “cigar” galaxy M82. (b&w)
Rough instrumental magnitudes 2014G = 14.8 R., 2014J = 11.1 R.
Both images were taken with the .56 meter reflector at sandlot Observatory.
