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.
! Thicker dovetail bars will require longer screws (see diagram).
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)
---
Want to buy your own screws? Choose the "none" option.
- You will need to purchase screws that are either 75 or 80mm long (or the equivalent in imperial).
- If you have a thicker dovetail, like the William Optics DSD then you will need an 80mm length screw.
---
What's included:
- Two 2.5" (64.80mm) tall riser blocks made out of PETG thermoplastic material.
- Two M6-1.0x75mm or 1/4-20x3" screws.
- If the "both" option is selected, then you will get four screws in total (metric & imperial).
