Abell 1367, the Leo Galaxy Cluster
This large galaxy group is estimated to be about 300 million light years away. A few of the largest and brightest of these galaxies can be seen in large amateur telescopes. Jim Mazur captured this image with a 14″ Meade LX850 telescope and an SBIG STF-8300M imager. Total exposure times were 273 minutes of luminance and 45 minutes each of red, green, and blue.
