Rare badge

Catalogue Reference

A Messier or Caldwell object whose official picture on Starbook is yours: the best-loved picture of it, at least 3 ratings averaging 3.5 stars, chosen every hour. Every object you have held counts, even after another picture takes it.

Earned the way points are: nothing on your own pictures counts, and both you and anyone whose action counts need a confirmed email and an active account. Badges stay once earned.
