Farpoint D-to-V Dovetail Adapter Assembly, Tall (Losmandy to Vixen)

Product Overview

The Farpoint D-to-V Dovetail Adapter Assembly (Tall) lets a telescope carrying a D-size (Losmandy-style) dovetail bar mount on a V-size (Vixen-style) mount. It is an assembly of Farpoint's 7″ D-size saddle bolted to a 7″ V-size dovetail bar: the V bar drops into the mount's saddle, and the D saddle on top clamps the telescope's bar. The tall version adds two spacer pucks that raise the assembly. Machined from aluminum with a black anodized finish, CNC-machined in the USA, published at 2.625 lb.

Who It's For

This is a good match if you…

• have a telescope on a D-size (Losmandy-style) bar and a mount with a V-size (Vixen-style) saddle
• want to keep the existing D bar on the tube rather than swapping it for a V bar
• move one telescope between mounts of both standards
• found the clamping knobs awkward to reach on a low-profile adapter and want the extra height the spacer pucks give

Key Features & Design

• Two-standard bridge: D-size saddle above, V-size bar below, converting a D-bar telescope to a V-size mount.
• 7″ D-size saddle: Farpoint's own 7″ saddle forms the upper half of the assembly.
• 7″ V-size dovetail bar: the lower half drops into any Vixen-style mount saddle.
• Two spacer pucks: the tall version's pucks raise the assembly for easier access to the clamping knobs in some mount configurations.
• Black anodized aluminum: machined from sturdy aluminum with a black anodized finish.
• Made in the USA: CNC-machined in the USA.

Mechanical Design

The two dovetail standards differ in width and wedge angle, so a bar of one profile cannot seat in a saddle of the other. This assembly stacks the two interfaces back to back: the V-size bar on the underside presents the narrower Vixen profile to the mount, and the D-size saddle bolted on top presents the wider Losmandy jaws to the telescope. Every load therefore passes through two clamped joints instead of one, which is why both halves run the full 7″ rather than a short block. The spacer pucks sit between the saddle and the bar and lift the saddle body clear of the mount head, which is what opens up finger room around the clamping knobs on mounts where the saddle would otherwise sit close in.

Recommended Uses

• Putting an SCT or refractor that already carries a Losmandy bar onto a Vixen-saddle mount.
• Sharing one optical tube between a large D-saddle mount and a smaller V-saddle mount.
• Travel rigs where the lighter Vixen-saddle mount goes out and the heavier mount stays home.
• Mount heads where clamping knobs sit close to the casting and the added height helps.

Compatibility and Accessory Notes

• Direction of conversion: telescope with a D-size (Losmandy-style) bar onto a mount with a V-size (Vixen-style) saddle.
• Opposite direction: a V-size bar onto a D-size mount is handled by the V-to-D adapter saddle in the same line.
• Mount side: any mount with a Vixen-style saddle that accepts a 7″ bar.
• Telescope side: any D-size Losmandy-style bar the 7″ saddle can clamp.
• Related saddles: the 7″ and 14″ D-size saddles, the 6″ Takahashi saddle, and the 7″ EQ6 / Atlas conversion cover the other mounting jobs in this line.

Good to Know Before You Order

• It converts one way. The assembly takes a D bar onto a V mount; the reverse case is the V-to-D adapter saddle.
• The assembly adds height. Raising the telescope above the mount head lengthens the lever arm on the mount, which is worth weighing on a mount already near its load limit.
• Load capacity is set by the mount. A Vixen-saddle mount is generally the lighter of the two classes, and the adapter does not change what the mount can carry.
• Only the adapter is included. The telescope's D bar and the mount are separate.
• Published weight is 2.625 lb. Shipping is calculated at 3 lb, the next whole pound.

Frequently Asked Questions

Which direction does it convert?

It puts a telescope with a D-size (Losmandy-style) bar onto a V-size (Vixen-style) mount. The V bar on the bottom drops into the mount's saddle; the D saddle on top clamps the telescope's bar. The opposite conversion is the V-to-D adapter saddle.

Is it difficult to install?

There is nothing to assemble. The V bar slides into the mount's saddle and is clamped, then the telescope's D bar slides into the saddle on top and is clamped. Both are the same motions used to mount a telescope normally.

What are the spacer pucks for?

The two pucks raise the assembly, and the extra height makes the clamping knobs easier to reach in some mount configurations. That is what distinguishes the tall version.

What is included?

The complete assembly: the 7″ D-size saddle, a 7″ V-size dovetail bar, and 2 spacer pucks. The telescope's D bar and the mount are the only other pieces involved.

Bottom Line

In short: a 7″ D-size saddle on a 7″ V-size bar with two spacer pucks, putting a Losmandy-bar telescope on a Vixen-saddle mount, CNC-machined in the USA and published at 2.625 lb.
