eta Persei
eta Persei is a bright double star, placed within a striking asterism. When I was writing my notes on this double, I found out the collecting the right data on individual stars is sometimes much more complicated than you think. I got some help from an Austrian astro-photograpeher, Peter Wienerroither. His image of eta Persei was a great help identifying all the components of eta Persei.
