Look for HD 227457 in the constellation Cyg. At apparent magnitude 10.03, a small backyard telescope will bring it into view.
Like any astronomical target, HD 227457 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 227457 scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 6 science badges — Variable star, Distant (over 1,000 light-years), Hot blue B-type star, Main-sequence star, Strongly variable 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.
