NGC 4725


Combination of 3, 3 minute exposures, Meade 416xt CCD.
8" f/6 newtonian telescope at prime focus.

NGC 4725 is a bright spiral galaxy in Coma Berenices, about 3 degrees south of the star 31 comae, and about 4 degrees east of NGC 4565. It is an outlying member of the Virgo cluster, and is easily visible as an oval patch of light with a bright nucleus in an 8" telescope. With a 12" telescope, some hint of the spiral arms can be discerned.

The galaxy to the right (south west) of NGC 4725 is NGC 4712. At magnitude 13.3, this galaxy is easily visible in a 12" telescope and makes a very good challenge for an 8".
