Triangular Telescope

Here is an interesting telescope with a triangular configuration. It appears to be an 8-inch and it has the viewfinder incorporated internally. The small hole to the side of the main aperture is for the viewfinder which is viwed through with the lower eyepiece. I noticed that the three legs for the pier seem to be somewhat on the short side. Of course it may be a short as can be allowed. Slide taken at the 1992 RTMC.
