Telescope Dovetail Saddle Clamp Mount Base for Vixen Style Dovetail

In this review the focus is a compact and functional saddle that adapts Vixen-style dovetail plates to tripods and heads. The Yueoct saddle is aimed at amateur and semi-pro telescope users who want a reliable, drop-in mounting method with flexible attachment options. The single biggest reason to consider it is the combination of dual locking knobs and multiple threaded mounting points, which make swapping optical tubes and securing the saddle to a tripod or equatorial head straightforward and stable during observing sessions.

Key Features

• Vixen-style compatibility: Accepts standard Vixen-style dovetail plates so most OTA rails fit without modification.
• Dual locking knobs: Two locking knobs provide improved clamping force and redundancy for steady support under load.
• Drop-in mounting: The saddle supports drop-in loading, allowing quick placement by tilting and lowering the dovetail plate into place.
• Multiple threaded holes: Center 3/8in threaded hole with 1/4in adapter and four M6 threaded holes give versatile attachment options to tripods and brackets.
• M6 and M8 countersunk bores: Four M8 countersunk bores and two M6 slots provide options for secure bolting with common spacing patterns.
• Included adapter: A 3/8in to 1/4in screw adapter is supplied to fit a wide range of tripod screws quickly.

Who It's For

This saddle fits observers who use Vixen-style dovetail plates and need a compact, sturdy adapter to mount optical tubes to equatorial heads or tripods. It is useful for those who value quick drop-in mounting and the ability to use both 3/8in and 1/4in tripod screws without additional parts.

It is less relevant for users who require integrated motorized features, extremely heavy payload capacity beyond typical OTA loads, or a very large dovetail base longer than standard Vixen rails; in those cases a heavy-duty clamp or purpose-built mount would be a better choice.

Pros & Cons

Pros

• Solid compatibility with Vixen-style dovetail plates for easy OTA swaps.
• Dual locking knobs increase clamping reliability and security.
• Multiple M6/M8 countersunk bores and threaded holes offer flexible mounting patterns.
• Included 3/8in to 1/4in adapter simplifies attachment to common tripod screws.

Cons

• Not intended for extremely heavy or oversized OTA loads where a larger saddle would be preferable.
• Does not include extra spacers or pads; fine-tuning alignment may require existing accessories.

Our Verdict

The Yueoct Vixen-style saddle is a practical, value-oriented adapter for observers who need reliable, quick mounting and broad tripod compatibility.
