Exactly my thoughts Robin.
I too thought this was a BAA meeting organised for it’s members. Certainly a larger venue would allow for the attendance of more members. I would like to attend next year’s one which I think has Exoplanets as it’s topic. If I can’t get into that one then after 51 years unbroken membership I would have to reconsider my position as a member.
However, if wee not careful this thread could descend to the unfriendly depths found on other forum sites.
