Stellarvue Lightweight 2.5" Riser Blocks with 1/4-20 Screws - Set of Two - RS-SET


Stellarvue Lightweight Riser Block Set with 1/4-20 Screws

Stellarvue Risers are a perfect solution when you want more room (2.5") between the dovetail plate or rail and your refractor telescope. This is particularly important with shorter telescopes (such as the Stellarvue 70 mm and 80 mm refractors) when a camera is mounted to the rear and it cannot be balanced on the mount. Using Stellarvue Riser Blocks and a longer rail that extends to the rear allows for adjustable travel to attain balancing over the focuser. Take a look at the included images showing how to connect and use the risers & dovetail. The screws pass through the dovetail rail (sold separately) from the back, then through the risers and finally, thread into the telescope's mounting rings. Tighten the screws and you'll be amazed at how rock solid this system is. By the way, if you do not have a longer dovetail, Stellarvue offers a kit with a Vixen-style dovetail or Losmandy-style dovetail.

The riser blocks, which lift your telescope and camera above the mount, are 1" wide by 2.5" high and are machined for strength and light weight in the Stellarvue factory in Auburn, California. This set, as mentioned above, comes with standard screws to attach to mounting rings with 1/4-20 threaded holes. Please measure the screws before using since some mounting rings have holes that go all the way through. If that is the case and the bolt is too long, it may scratch your OTA, which would be a shame. To make sure this doesn't happen, insert the bolt through the dovetail and riser block and measure the length of the bolt that is left. If your ring's thickness is more than that of the leftover thread, you will be fine. If not, you will need a shorter bolt!
