Twisted Galaxies
NGC 3718, NGC 3729 and friends are a two groups of interacting galaxies. The closest are NGC 3718 and NGC 3729 at a distance of a mere 52 million light years away. It is thought that the two galaxies are interacting thought they are separated by 150 thousand light years. The smaller galaxies toward the bottom of the photo is known as the Hickson Group 56 and consists of five separate galaxies. These galaxies are located some 350 million light years distant! I believe this the first photo I have taken that show two separate interacting groups. Taken with my SCT at f/6.3.
