IC 1623 is the sort of galaxy that Vorontsov-Velyaminov would have called a "nest" if he had seen the DSS2 images. As is, he called it an interacting pair (it is VV 114 and Arp 236). There are eight or nine interacting components most easily seen in the DSS2IR image. The positions I've taken refer to the approximate middle of the five or six bright blobs in the western component, and the middle (brightest) of the three eastern components.

The pair has been well studied; see NED for the details. The eastern galaxy is an infrared source, while the western is a "starburst" system with many bright star-forming regions knots. The beautiful Pan-STARRS color image is a perfect demonstration of the differences between the two galaxies. After some consideration, I've adopted positions for some of the knots from the Pan-STARRS list. These are more or less representative of the central regions of the galaxies and the plumes/knots associated with them.
