Small, Medium and Large

Hi White Rabbit & All,

Hmmm ... vexed question. I think you're gonna get quite a few different answers on this because there is no formal definition or even broad consensus. I try not to use these terms (so far as possible) in my articles for that very reason. This is my take on it -- with "overlaps" and an extra category.

15cm (6") is the largest small telescope or alternately the smallest medium-sized 'scope.

30cm (12") is the largest medium-sized 'scope or alternately the smallest large 'scope.

50cm is the largest large 'scope or alternately the smallest huge 'scope.

+50cm is huge in anyone's language.

Best,

Les D
