Look for HD 180196 in the constellation Sgr. At apparent magnitude 10.78, a small backyard telescope will bring it into view.
Like any astronomical target, HD 180196 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.
HD 180196 scores 67 points on Spacedle's rarity scale, which places it in the epic tier. Another 11 points would lift it into a rarer tier.
That score comes from 7 science badges — Variable star, Toward the galactic centre, On the zodiac, S-type star (zirconium giant), Deep red star, Dramatic variable (over 2 magnitudes) and A named variable star — 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.
