Appearance
Obvious major error? It appears IMHO that the description in the first illustration has a major error and should read "7" instead of "8" pm. This was an easy error to make since the number "8" is prominently visible. JdelaF (talk) 21:01, 14 August 2016 (UTC)
Cassiopeia?
[edit]I believe, from tests using a cardboard printing of this image, that it is set for use with a star in Cassiopeia, apparently Alpha (aka Schedar). Can anyone confirm?
