Click to go to Sirius Observatory Main Page3 INCH BRASS TUBE TELESCOPE



This telescope (larger or back one) is part of the cage assembly that came with the Gaertner coelostat, 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.
