Description

These risers lift your entire telescope 2.5" (64.80mm) above the dovetail bar, which as a result allows for the full rotation of the focuser, and the ability to balance the scope properly. 

Risers also prevent off axis guiders & filter wheels from pressing against the ground when the scope is not being used. 

Note:

  • Intended for use on refractors with an aperture of 85mm or smaller.
  • Rated for use down to -25C (-13F) and up to 80C (176F) temperatures

---

Compatibility is based on the type of thread your tube rings use. The majority of refractor rings use an M6 thread, but some brands such as Stellarvue and Sky-Watcher use a 1/4-20" imperial thread.

  • Select the relevant screw type for your refractor.
  • If you are unsure what screws you need, both types can be purchased (2.5-RISER-BOTH)

---

 

What's included:

  • Two 2.5" (64.80mm) tall riser blocks made out of PETG thermoplastic material.
  • Metric: 2x M6-1.0x75mm and
                 2x M6-1.0x80mm
  • Imperial: 2x 1/4-20x3" and
                    2x 1/4-20x3.1/4"
  • If the "both" option is selected, then you will get 8 screws in total (metric & imperial screws + extra length ones).

Amazing deal for half the price of competitors

I have been using these risers for about a month and a half now and they are very solid. I highly recommend for anyone wanting high risers with a refractor.

Quality product at a great price!

Ordered a pair a few months back for my 80mm Triplet. Super solid, and has plenty of clearance for all my attached accessories! Would buy again!

Ordered the 2.5 inch refractor risers

Worked perfect to elevate my William Optics 70mm refractor to give me ability to rotate without hitting the dovetail or mount. Strong and great quality.
