so this is a telescope you built?
Yes it is. Most of my scopes are home-made. This one features a surplus 50mm f/9 objective, PVC tube, lathe-turned endpiece. Commercial diagonal. Lathe-turned PVC objective cell. I do all my turning on a hobbyists mini-lathe. Harbor Freight has one on-sale now for $399. The eyepiece is one of my favorites. I did a whole series of aluminum barrel eyepieces about ten years ago. Again, turned on the mini lathe. This is the one I use side-by-side with my PST, so I can have white light views of the sun in addition to H-a, at a similar image scale. I've got dozens of home-built scopes, lots of small refractors among them.
