Ran the galaxy cluster through Astrometry.net.

Over 20 identified objects...

Astrometry.net link: Abell 2151.

Centre (RA, hms): 16h 05m 37.559s
Centre (Dec, dms): +17° 46' 21.243"
Size: 47.8 x 31.8 arcmin
Pixel scale: 0.737 arcsec/pixel

And here's the snapshot from SkyTools.

There are quasars within the frame but I can't identify them in the digital frame given the noise.
