Trivia
What it actually is
- What it actually is. A star cluster still wrapped in the nebula that made it — newborn stars lighting up their own birth cloud.
Find it in the sky
- How to spot it. At magnitude 7.2 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Cepheus.
- Northern sky. It rides the northern half of the sky — an easier target the further north you are.
- Best time of year. It stands highest in the middle of the night around September — that's when to go looking.
Its true colour
- Its true colour. The stars are blue-white and brand new; the gas around them glows red, ionised by their ultraviolet glare.
How we came to know it
- The New General Catalogue. Its NGC number comes from J. L. E. Dreyer's 1888 catalogue, itself built on decades of sky sweeps by William Herschel and his sister Caroline.

Why NGC 7380 is a rare cluster
NGC 7380 scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 6 points would lift it into a rarer tier.
That score comes from 6 science badges — Star cluster, Bright deep-sky object, Cluster still wrapped in its gas, Never sets (northern circumpolar), Big on the sky and Coming towards us — 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.
