Comet Nishimura and Denebola AB

Yesterday evening, Mrs H and I shared an hour in the local graveyard, which strangely provides our best unobstructed view of the horizon. We were keen to see comet Nishimura before it set but try as we might with our trusty binoculars the sky brightness defeated us. More by desperation than design I captured a number of images using my DSLR, a stock zoom lens at f=55mm and ISO400. I'm pretty certain the bright star is Denebola in Leo Major and the smaller and fainter dot higher and to its left may be Comet Nishimura.
