Supernova sn 2017gxq in Ursa Major (2)

Another picture of sn 2017gxq in NGC 4964 (Ursa Major). Now parent galaxy is visible as a small comet-like nebula (with longer total exposure and better atmosphere). My estimation gives the brightness of the supernova is comparable with the total brightness of the galaxy!
