Arp 104

Hi

Arp 104 is made up of two galaxies, NGC 5216 and 5218 in Draco.  Arp cataloged them as "elliptical connected to spiral".  These two are also sometimes referred to as Keenan's System (Philip Keenan imaged them in the 1930s showing the bridge between them):

The spiral galaxy near the bottom of the field is NGC 5205

I like the "light bridge" connecting the two. The coloring is very nice.

Gregg - Those thin gravitational streamers are tough to capture. Great job and thanks!
