Description

A more exotic object. Interrupted the exposure of Arp 214, I have decided to test my setup on this objects in the early hours of the night. The bridge of intergalactic material is 124000ly long and visible quite well, even in some moonlight and with very poor seeing.

Wikipedia: "Arp 104, also known as Keenan's system, is entry 104 in Halton Arp's Atlas of Peculiar Galaxies catalog for spiral galaxy NGC 5216 and globular galaxy NGC 5218.[2] The two galaxies are joined by a bridge of galactic material [...].

In 1790 William Herschel discovered the galaxies, and in 1926 they were studied by Edwin Hubble.[2] In 1935 Philip C. Keenan first published a paper about the bridge connecting the galaxies,[2][10] which was rediscovered in 1958 at the Lick and Palomar observatories."
