3" F15 Alt-Az Telescope



A nice 3" F15 on a custom made Alt-Az mount.  While I am not using the cage, it makes a nice alt-az scope.

This telescope (larger or back one) is part of the cage assembly that came with the Gaertner spectroscope, but is a fully functional telescope all by itself. It was missing the lens when I got it. I found a 3" F15 Unitron lens which fit.
