NGC 1789 is an uncommon cluster. It sits in the constellation Men and shines at apparent magnitude 13.06.
A globular cluster: hundreds of thousands of stars packed into a ball a few dozen light-years across, orbiting far out in the galaxy's halo.
Look for NGC 1789 in the constellation Men. At apparent magnitude 13.06, it takes a larger telescope or a long-exposure image to capture.
Like any astronomical target, NGC 1789 is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
NGC 1789 scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.
That score comes from 3 science badges — Star cluster, Globular cluster and Faint fuzzy (mag > 13) — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
