I know the guy, he is a very reliable seller, though not always very responsive to emails.

Thanks for the link!! Looking at his for sale items was more looking through a old photo album. Brings back my planetarium days!
Thanks

Ha! That it does, how many auctions on ebay can you find that have an entire planetarium dome in a box for sale or an MS-10 for that matter. He's a neat guy to work with too, I did some contract work for him many years ago and it was great fun tearing a theater apart and putting it all back together again. So what theater did you work at?

Gates Planetarium, Denver, CO
I Started volunteering when I was 14 ( I am 34 now, ugh) and was a staff guy for two years. Gates is responsible for my laser addiction
A couple of years ago they totally gutted Gates and rebuilt it from ground up, totally state of the art. It turned out very well. Any way I could have had the dome if I took it down and also the Minolta. My problem was I didn't have a place to store it. I always wanted to build a night club with that stuff.. I did get the telsa from the zap show

Ha! Just like the late Alexander Breast (Planetarium) is responsible for my addiction. I started there when I was 16, now I'll be 30 in a day, where has the time gone... Best job I've ever had, just didn't pay anything. Sadly, the theater now needs a complete overhaul as it has been just run into the ground. And there seems to be no interest on the part of the museum to do anything about it, except patch work. Last I heard they ran for some time with no southern hemisphere stars and now aparently no bright stars. Shame really, its a great instrument, just not very well cared for. Good job getting the tesla coil! I would have drove from florida to pickup the minolta had I known, wife wouldn't have been happy, but it would have looked great in my garage I think!![]()
