Hi,  Just a bit of research, but absolutely no need to reply.  Now it goes without saying, but I need to say it anyway, that everyone else on this forum fits definition a) below. If you know quite well a few fellow astrophotographers, and please don't mention names, could you categorise them into one or maybe 2 of these definitions a) Someone well rounded, intelligent, discerning and unflappable. b) Someone who takes up the hobby partly as an excuse to explain their grumpiness. c) Someone who has unshakeable, eternal optimism.  d) Someone into astronomy but with a tendency towards masochism. e) Someone with a good sense of humour/humor.  f) Someone who is placid but shows signs of slightly elevated self-oriented perfectionism.  Maybe you can come up with another definition.  I'm not revealing which of b, c, d or f I fit into.  Cheers,  Ray
