Farpoint Dovetail System · Complete Bar Kit
Everything to put your Celestron 8″ RASA on a D-size saddle — bar, radius blocks, and hardware in one kit.
This complete kit mounts the Celestron 8″ RASA astrograph on any D-size (Losmandy-style) saddle. The 19″ dovetail bar pairs with radius blocks machined to match the 8″ RASA tube, spreading the clamping load across the curve of the optical tube instead of pinching it at two points — a solid, stress-free foundation for the fast wide-field imaging the RASA was built for. Mounting screws included; CNC-machined in the USA from black anodized aluminum.

Frequently Asked Questions
What's included in the kit?
The 19″ D-size dovetail bar, radius blocks machined to match the Celestron 8″ RASA tube, and the mounting screws — everything needed to attach the bar to your optical tube. The telescope itself is not included. The bar drawing shows the hole pattern and measurements.
What mounts will this work with?
Any mount with a D-size (Losmandy-style) saddle — Losmandy, and the many mounts that accept the wider D standard. Mount still has a small Vixen saddle? Our D-size saddles and conversions upgrade it.
Why radius blocks instead of bolting the bar straight on?
The RASA tube is round; the bar is flat. Radius blocks are machined to the exact curve of the 8″ RASA tube so the clamping load spreads across the contact surface instead of concentrating at the bolt holes — a stiffer connection that doesn't stress the optical tube.
