Spacer 2.5"

With these risers, you can raise your entire telescope 65 mm above the dovetail rail, allowing the focuser to rotate fully and the telescope to be properly balanced. Risers also prevent off-axis guiders and filter wheels from pressing against the ground when the telescope is not in use.

The elevation extends the usable time well beyond the meridian flip, in some cases eliminating it completely. With short-focus optics, the meridian flip is completely eliminated, allowing you to photograph the entire night without a meridian flip.

To mount the risers, insert the screws through the riser blocks and then screw them to your tube clamps and prism rail.

Warning regarding screw length: Some tube clamps have threaded holes that go all the way through the ring. If you use a screw that is too long, the telescope tube may be damaged. Therefore, measure the length before use. Insert the screw through the rail and the riser block and measure the length of the screw that protrudes from the top of the riser block. The screws supplied will fit most of the most common tube clamps on the market.
