These accessories are new and were never used, they are based on the tube rings used for the Unitron 4" refractor:
2 ea., guidescope hinged tube rings, the guidescope mounts themselves are not included, just the felt-lined rings, with two tapped holes about 65mm apart to mount the guidescope mounts.
1 ea., solar screen tube ring. The felt-lined hinged ring, plus the mount (included) that holds the solar screen shaft (not included), locks in place with the set screw.
