Re: replicating "old" science



Jerry,

You should make the distinction that you are referring to professional
astronomy educators, not professional astronomy researchers. Professional
observatories doing original research are quite a different matter.

With that distinction made, I wholeheartedly agree with you. Many colleges
and universities could benefit from the experience of advanced amateurs in
their area if they want to begin or improve an observing program. Many
professional astronomers don't have much hands-on experience with
telescopes.
