The proposed description of this site is quite weak and doesn't provide any real direction. Personally, I think amateurs (and their equipment) have to be explicitly included, because astronomy, perhaps more than any other science, relies on amateurs for observational data and other input. A great example is the list of observatories, many amateur, maintained by the IAU Minor Planet Center at cfa.harvard.edu/iau/lists/ObsCodesF.html - mine is code J58. While amateur astronomers represent a wide spectrum of interests, the top end certainly overlaps the professional arena. – Tim Long May 27 '10 at 15:36

I think the question of whether spaceflight and space exploration are on- or off-topic needs to be explicitly incorporated into the charter. The overlap between "people interested in astronomy" and "people interested in spaceflight" is very large, but not necessarily 100%. – Larry OBrien May 29 '10 at 18:37

There may be three populations of questions here, Professional Astronomy and Astrophysics, Practical Amateur Astronomy and Space Flight and Exploration. – Chris Rowland May 31 '10 at 7:37
