My best and only classic scope is my Celestron C5+, complete with single fork arm equatorial mount and tripod. It was manufactured in 1993 and is a complete package; light shield, carrying case, hand controller with dec motor.
I really hope it can be classified as a classic because I really am fond of this particular scope.
I second your choice. While I have had a few more scopes, I'm still not a collector and only have 3-4 scopes at a time as a maximum, before I start to sell something off again.
My C5 Classic is the same scope that you have, the early 1990s white tube with the beefy single arm mount, but mine came with the basic AC drive. Of all the scopes I ever had, this is maybe my most definite all-time keeper. I love the way how it operates, so much nicer mount than the ETX-125 that I had. I also love the looks of the C5 and I also love looking through the C5, very good optics. And also it's not expensive compared to many other scopes which also can help to make a scope a long-term keeper.
I love to bring it to my mother's house when we visit her for Christmas and set it up for some quick looks of the Moon, planets, Pleiades, Orion nebula or whatever else can be found quickly, which is where this photo was made some years ago.
I'm also very fond of mine! Thomas
