Dave Samuels, one of FPOA’s volunteer astronomers, has captured some images of Nova Cygni 2008 #2 (V2491 Cygni) with his Canon 20D on at 1920mm focal length from his backyard in Pleasanton, CA. I’ve quoted his email below with additional images.
Here is an image I took this morning from my backyard In addition, I cropped and labeled it so that you can clearly see the nova and the star next to it. Also included is the DSS image and a cropped and aligned version the same size as the cropped image that I took this morning. It is likely that one of the two faint stars (around mag 18 – 20) is the one that went nova (DSS image pixel location 726,754 or 722,757). The limiting magnitude of my image is 17 at best, 18 with a little imagination.

Turns out that Chi Cygni is about 1 degree, 40′ to the north east of this location. The bright star at the top-right is HIP 96977, mag 5.90 (according to StarryNight). At the center, just above and to the right of the nova is TYC 2660-1754-1, mag 10.25. There is a very faint star in my image just peeking above (north) of the nova at pixel location 1596,1250 (est. mag 16+/-), and the nova is located at 1595,1567.
