Description
Product Overview
The Alstar Tri Finder Scope Holder is engineered to give astronomers and hobbyists the flexibility to attach up to three aiming devices on a single telescope. Constructed from black anodized aluminum, the bracket combines corrosion‑resistant durability with a feather‑light weight of just 7.6 ounces. The anodized finish not only protects the metal but also reduces glare during night‑time use. Designed for a standard telescope dovetail slot, the holder features a telescope‑mount style clamping system that secures each finder with two set‑screw clamps, ensuring stable positioning even under windy conditions. The package includes three pre‑drilled mounting points, a quick‑release lever for fast changes, and all necessary hardware for a tool‑free installation.
Usage
This holder shines in a variety of observing scenarios. Visual astronomers can mount a low‑power finder scope, a red‑dot reflex sight, and a green laser pointer simultaneously, allowing rapid target acquisition across the night sky. Astrophotographers benefit from the ability to attach an auto‑guider, a mini guide scope, and a polar alignment scope without swapping accessories between exposures. The compact design fits comfortably on both refractor and reflector telescopes, making it suitable for backyard stargazing, field trips, and portable setups.

FAQ
Can I use this holder with a Dobsonian telescope?
Yes, as long as the Dobsonian has a standard dovetail plate, the holder slides into the slot and provides three mounting points for your accessories.

Absolutely. The bracket’s dimensions are designed to accommodate the common Vixen/Synta 1.25‑inch and 2‑inch finder shoe standards.
Do I need any tools to install the holder?
No special tools are required. The included set‑screws can be tightened by hand or with a standard small screwdriver, and the quick‑release lever operates without tools.
Will the anodized finish fade over time?
The anodized coating is engineered to resist UV exposure and moisture, so it retains its dark finish for many years under normal outdoor conditions.
Can I mount a camera guide scope on this holder?
Yes, the holder’s robust clamps can secure lightweight guide scopes or camera adapters, making it a versatile addition for astrophotography setups.
