HCG 10

Hickson Compact Group 10

HCG 10 is a compact group of four galaxies in the constellation Andromeda, located about 200 million light-years away. The group consists of three spiral galaxies (NGC 536, 531, and 542) and one elliptical galaxy (NGC 529), with NGC 536 and NGC 531 strongly interacting with each other. These gravitational interactions distort the spiral arms and trigger enhanced star formation within the group. Eventually, the four galaxies will likely merge into a single larger galaxy.

Observation Data

Location:Pollux Observatory, Zuidlaren
Date:2024-10-02
Information: Hickson compact groups are actually too small for my telescope. However, it turns out that when magnifying the photo, the group members are often still quite visible. Because these objects are very interesting, I photograph them anyway.
