Its story

20 Persei is an F-type star about two hundred and thirty light-years away, yellow-white, somewhat hotter and more luminous than the Sun. It inhabits the body of Perseus, far from Algol's dramatic blinking but sharing the same patch of autumn sky. Its light, which set out when refracting telescopes were beginning to displace reflectors in astronomical work, now arrives clean after the long journey.
