Chuck, I see all sorts of observers at star parties. Some folks tend to set up quietly and endure the crowds that drift their way. They pass very little information on to their guests: perhaps that quiet approach is just the ticket for some people. Other astronomers are crowd magnets and seem really to enjoy passing knowledge and excitement along to others. I certainly enjoy watching someone light up when they see something for the first time; I'm equally happy when they've headed home and left me with a little time for myself. I certainly don't think any kind of astronomer is excluded or should feel excluded.

I've got a few El Cruddo brand plossls that are perfect for star parties. First-time viewers are thrilled with what they see and I don't sweat it when some kid puts his thumb on it. I also take a non-goto scope, since there's no harm done if somebody inadvertently knocks the scope out of alignment. A lot of it is just being prepared for Murphy and accepting the fact there will be little foos. You can then relax and enjoy the companionship.
