This is Caldwell 28, a fairly bright open cluster located 1,200 light years away in Andromeda. The two bright stars to the lower left are HR 557 and HR 556, both double star systems. This cluster was discovered in 1786 by William Herschel and at magnitude 5.7, can be seen with binoculars. It is 1.5 times the diameter of the full moon, and if you download the picture and zoom in, you will find several Galaxies located behind the cluster. How many can you find?
