Object name: NGC3982
Thanks to having now over 1500 narrow-angle fields in my image library, all covering only about one-fifth of a square degree of sky, I'm now starting to find I can mosaic a current image to a prior one taken years earlier. As it happens this image allowed me to do that. I took this one for the disconnected arm on the galaxy and the 2011 image for a supernova in NGC 3972. I did reprocess this one somewhat as the color balance in 2011 was done differently and wasn't all that accurate as I usually can achieve today.
