I thought I had better refresh the venue as some newer members may not know exactly when it is, so here is a map of Otford village for the uninitiated.... and hope to see everybody there on the 14th November for the talk and observing.
See you all soon, Doug.
If you look at the observing evening entries on the main website you'll find a map there. You can even ask it to give you directions...
