Something is not quite right with this image. Some of the stars are in sharp focus, while others are not. Look closely and you’ll see that each of the fuzzy ‘stars’ is in fact a galaxy, each one home to billions suns. Spread across this field image is members of the Perseus galaxy cluster. From left to right NGC 1272, 1275, and 1278 are the 3 moderately bright galaxies near the center of this field of view and the main cluster lies roughly in a line to the lower right and upper left, but the entire field is sprinkled with galaxies of every sort. Located just east of Algol, this is simply a wonderful field to spend some time with visually or with the help of a camera.
