Farpoint Extra 3 Pound Counterweight

Product Overview

The Farpoint Extra 3 Pound Counterweight is a single 3 lb weight of 4″ diameter — the same weight that ships inside the Farpoint Dovetail Weight System 1 and System 2. It stacks onto the 3.5″ screw already carried by those kits, so ballast is added to an existing setup rather than replacing it. Made in the USA.

Who It's For

This is a good match if you already run a Farpoint Dovetail Weight System and your imaging train has grown — a heavier camera, a guide scope or more glass at the rear cell — so the ballast already on the bar no longer brings the tube into balance.

Key Features & Design

• 3 lb per weight: Ballast is added in 3 lb steps, so balance can be trimmed rather than jumped.
• 4″ diameter: Identical in size to the weights supplied with Weight System 1 and System 2.
• Stacks on the existing screw: It threads onto the 3.5″ mounting screw that comes with the weight systems.
• Made in the USA: Finished in black powder coat or bright zinc, depending on the production run.

Recommended Uses

• Extending a Dovetail Weight System 1 from 3 lb to 6 lb of ballast.
• Extending a Dovetail Weight System 2 beyond its 6 lb of factory ballast.
• Rebalancing after a camera, filter wheel or guide scope upgrade adds mass at the rear cell.
• Keeping a spare weight in the case for rigs that get reconfigured between sessions.

Compatibility and Accessory Notes

This is the weight on its own. It works with the Farpoint Dovetail Weight System 1 and the Weight System 2, which supply the FDA quick-release saddle and the 3.5″ mounting screw the weight stacks on; that saddle is a D-size (Losmandy-style) clamp. Ontario Telescope carries both systems if one is not already on the rig. Tell us which weight system you are running and we'll confirm the fit.

Good to Know Before You Order

• Weight only. No saddle and no mounting screw are included; those come with Weight System 1 or System 2.
• Finish varies by production run. A weight ordered now may arrive in black powder coat or bright zinc, so it can differ in appearance from the weights already on the system. The difference is cosmetic and the weight and fit are the same either way.
• Screw length sets the stack. The 3.5″ screw supplied with the weight systems determines how many weights can be stacked at once.

Frequently Asked Questions

Is it difficult to install?

The weight threads onto the mounting screw already on the FDA saddle. No tools and no adjustment to the dovetail clamp are involved.

Does it work on its own?

It is the counterweight only. The FDA quick-release saddle and the 3.5″ screw it mounts on come with the Dovetail Weight System 1 or System 2.

How big is the weight?

3 lb, 4″ in diameter — the same weight supplied with the Dovetail Weight Systems.

Why is the colour different from my other weights?

Weights are finished in either black powder coat or bright zinc plating depending on the production run. The finish is cosmetic; weight and fit are identical either way.

Bottom Line

In short: a 3 lb, 4″ expansion counterweight made in the USA that stacks onto the saddle and screw of an existing Farpoint Dovetail Weight System, adding ballast in 3 lb steps as the imaging train grows.
