Everything to put your Celestron 8″ SCT on a D-size saddle — bar, radius blocks, and hardware in one kit.
This complete kit mounts the Celestron 8″ SCT on any D-size (Losmandy-style) saddle — and it also fits the HD8. The 13.5″ dovetail bar pairs with radius blocks machined to match the 8″ tube, spreading the clamping load across the curve of the optical tube instead of pinching it at two points. Mounting screws included; CNC-machined in the USA from black anodized aluminum.

Frequently Asked Questions
What's included in the kit?
The 13.5″ D-size dovetail bar, radius blocks machined to match the Celestron 8″ tube, and the mounting screws — everything needed to attach the bar to your optical tube. It also fits the HD8. 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 SCT tube is round; the bar is flat. Radius blocks are machined to the exact curve of the 8″ 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.
