Farpoint Dovetail Radius Blocks - Celestron 14 Inch SCT

Product Overview

The Farpoint FDC14R is a set of dovetail radius blocks machined to the curve of the Celestron 14″ SCT. They fit that tube only, and they work with a D-size (Losmandy-style) dovetail bar you already own — which is what makes them the economical route when a bar is moving from one scope to another rather than being bought new. The blocks are CNC-machined in the USA from black anodized aluminum and weigh 0.688 lb.

Who It's For

This is a good match if you already have a D-size Losmandy-style dovetail bar in hand and want to move it onto a Celestron 14″ SCT, rather than buying a second complete kit. It also fits the case where your C14 has a bar but the original blocks are worn, missing, or were machined for a different tube.

Key Features & Design

• Machined for the C14: Cut to the exact curve of the Celestron 14″ SCT tube, and fitting that tube only.
• Blocks on their own: Supplied without a bar, for use with the D-size dovetail you already have.
• Black anodized aluminum: Aluminum stock with an anodized surface layer.
• 0.688 lb set: The published weight of the blocks, which adds to the mounted load along with the bar and tube.
• CNC-machined in the USA: Produced on CNC equipment at Farpoint in the United States.

Mechanical Design

A dovetail bar is flat; an SCT tube is round. Bolted directly together, the two touch only along a narrow line, and everything the mount does — slewing torque, tracking load, the weight of an imaging train hanging off the back — is carried at the bolt holes. Radius blocks sit in that gap. Each is machined to the exact curve of one specific tube, so the block's inner face meets the C14's outer surface across its whole area and the clamping load spreads over that contact patch instead of concentrating where the fasteners pass through. The blocks are what let a flat bar behave as though it were made for a round tube, and why a set cut for one tube diameter will not serve another.

Recommended Uses

• Moving a D-size dovetail bar from another telescope onto a Celestron 14″ SCT.
• Replacing worn, damaged, or missing radius blocks on a C14 that already carries a bar.
• Building a second mounting setup for a C14 without duplicating the bar.
• Restoring a flat-to-round interface on a C14 where blocks machined for a different tube were substituted.

Compatibility and Accessory Notes

These blocks are machined for the Celestron 14″ SCT and that tube alone — the curve is specific, so a set cut for a different diameter will not seat correctly. They are used with a D-size (Losmandy-style) dovetail bar, the wider of the two common dovetail standards; V-size (Vixen-style) bars are the narrower format and are a different fitting. The blocks install between the bar and the optical tube. If you do not already own a bar, Farpoint's complete Celestron 14″ SCT kit includes the bar, the blocks, and the mounting screws in one package. Farpoint publishes the blocks as a standalone item precisely for the case where the bar is already in hand. If you are unsure whether your tube or your existing bar matches, tell us your telescope model and the bar you have and we'll confirm the fit.

Good to Know Before You Order

• The fit is exact to one tube. The radius is machined for the Celestron 14″ SCT; a C11, a C9.25, or any other diameter takes its own matched set.
• No bar is included. This listing covers the blocks; the D-size dovetail bar comes from your existing hardware, or from the complete C14 kit.
• They are D-size hardware. V-size (Vixen-style) bars are the narrower standard and are a separate fitting.
• The set weighs 0.688 lb. Shipping weight is rounded up to 1 lb, so ordering this alongside other small items can overstate a multi-item cart's total.
• Farpoint publishes no separate dimensioned drawing for the blocks. The specification is the tube they are cut for — the Celestron 14″ SCT — rather than a set of block measurements.

Frequently Asked Questions

Is it difficult to install?

No. The blocks sit between your dovetail bar and the tube, and the assembly bolts through to the C14's existing threaded holes with hex keys. Nothing is drilled and nothing is modified.

What do radius blocks do?

They bridge the gap between a flat dovetail bar and a round optical tube. Each set is machined to the exact curve of a specific tube, so the clamping load spreads across the contact surface instead of concentrating at the bolt holes.

Will these fit my telescope?

They are machined for the Celestron 14″ SCT only. For a different model or size, the matched set for that tube is the one to use, and we can point you to it if you tell us which scope you have.

Do I need anything else?

Just your existing D-size dovetail bar — the blocks install between the bar and the optical tube. Where no bar is on hand, the complete Celestron 14″ kit supplies the bar, blocks, and screws together.

Bottom Line

In short: a 0.688 lb set of black anodized radius blocks CNC-machined in the USA to the curve of the Celestron 14″ SCT, letting a D-size Losmandy dovetail bar you already own mount cleanly on that tube.
