This image has captured a small-scaled galaxy group seen at the eastern edge of Cancer. You can find out by tracing 8.6 degrees east from an major open cluster of the Praesepe (M44). Two major galaxies of NGC2804 and NGC2809 are paralleling in north south direction in 9 arc minutes apart. The both are 2 arc minutes-sized lenticulars, and several minor galaxies are scattered.
