I was talking to Jim Hysom at the Webb Society meeting last December at the IoA. Jim said he often still goes to Cambridge AS meetings, so you might catch him there if you wanted to chat with him.The f/3.9 20" mirror in my Dob was made by Jim. And I went to do a star party at a local school recently, and they carted out this 8" or 10" reflector, which was an AE Optics skeleton scope, just like David describes.Callum
