iOptron Dovetail Plate - 115mm universal
- 115mm Overall Length
- Universal Vixen-Style Profile
- Ideal for Guide Scopes and Finders
- Provides a Secure Mounting Platform
This universal dovetail plate provides a rigid, 115mm long mounting platform for securely attaching finderscopes, guide scopes, or other accessories to your telescope's saddle.
Designed to fit the industry-standard Vixen-style (V-style) saddle, this dovetail plate ensures broad compatibility with a wide range of telescope mounts and mounting clamps. Its compact 115mm length is ideal for smaller, lighter accessories that don't require the long footprint of a primary telescope tube.
This plate serves as a solid interface for guide scopes, large finders, or piggybacked camera systems. While its 115mm length provides a stable base for these items, it is not intended for mounting the primary tube rings of larger telescopes, which require a longer plate for proper balance and stability.
This 115mm dovetail plate is primarily used to mount auxiliary equipment onto a telescope system. Common uses include attaching a guide scope for autoguiding, a finderscope for locating objects, or a piggyback adapter for a DSLR camera.
The term "universal" generally refers to the Vixen-style (V-style) dovetail profile, which is the most common standard for small to medium-sized mounts. This plate should fit any mount equipped with a V-style saddle. It will not fit in a wider Losmandy-style (D-style) saddle without a V-to-D adapter.
Possibly, but it depends on the tube ring spacing of your refractor. A 115mm plate offers limited room for adjustment. It is best suited for "clamshell" style single-ring mounts or very small telescopes where the tube rings can be positioned close together. For most refractors, a longer plate is recommended for better stability and balance.
Yes, this is an excellent application for the 115mm plate. You can attach it to the top of your 8" SCT's existing rail (or via a dedicated adapter), then mount a ball head or piggyback adapter to the plate. This provides a secure platform for wide-field astrophotography with a DSLR while your main telescope tracks the sky.
In this context, "universal" refers to the dovetail's physical profile, which is designed to match the Vixen-style standard used by сотни of telescope mounts and accessories. It does not mean it will have the correct screw holes for every possible accessory out of the box; it refers only to the V-shaped profile that fits into the saddle.
Dovetail plates of this type typically feature a combination of threaded holes and/or a central slot. You attach your accessory (like a guide scope ring or a ball head) to the plate using the appropriate screws (commonly 1/4"-20 or M6). The slot provides flexibility in positioning the accessory for proper balance.
