These Astrodymium 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 92mm or smaller.
- Rated for continuous use down to -25°C (-13°F) and up to 55°C (131°F) ambient conditions.
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. We do not have compatibility info for the many telecopes on the market, so you will need to check your tube ring specifications before purchase.
- Select the relevant screw type for your refractor.
- If you are unsure what type of screws you need, both can be purchased for an additional cost.
What's included:
- Two 2.5" (64.80mm) tall riser blocks made out of PETG material.
- Two M6x75mm or 1/4-20x3" screws.
- If the "both" option is selected, then you will get four screws in total (metric & imperial).
