EYSDON Telescope Guide Locking Rings PLUS

CNC Machined Aluminum | Stable Guide Scope Mount | Multiple Inner Diameters (40 - 110mm) | Anti - Scratch, Anti - Wobble Design

Parallel Guide Scope Installation Made Easy!

• For astrophotography enthusiasts, EYSDON Guide Locking Rings PLUS solves the headache of parallel guide scope mounting simply & affordably. Whether you’re guiding with an 80mm refractor or other scopes, achieve stable, accurate alignment for stunning long - exposure shots.

1. CNC Precision Machining

• Crafted from solid aluminum blocks via advanced CNC machining, these guide rings boast ultra - high mechanical precision. Every dimension, from the 14mm side width to the precisely cut M6 screw holes, is engineered for a perfect fit — ensuring your guide scope stays rock - solid, no wobbles, no shifts.

2. Premium Aluminum Treatment

• After machining, the aluminum undergoes sandblasting for a smooth, burr - free surface. Then, hard anodizing boosts hardness, resists oxidation, and gives the ring its sleek, durable red finish. This isn’t just a mount — it’s a long - lasting investment for your astro gear.

3. Anti - Scratch & Secure Locking

• All 3 locking screws feature rubber tips — no more worrying about scratching your guide scope during setup. Tighten with confidence, knowing your equipment is protected while achieving a firm hold.

4. Anti - Wobble Cutting Design

• The ring’s cutting - edge design (both the screw holes and contact surfaces) eliminates wobble when attached to your base. Plus, the non - curved base hole ensures a flat, stable connection — say goodbye to shaky mounts that ruin your framing.

5. Optimized Width & Thickness

• 14mm Width PLUS: Wider contact surface (14mm side width) means more stability. Your guide scope sits steady, even during long exposures or on windy nights.
  

• All - Metal Thickness: Full - metal construction (side thickness 4.5mm) resists deformation. This ring won’t bend or flex, keeping your alignment precise trip after trip.

Available in multiple inner diameters to match your guide scope:

Choose the size that fits your guide scope’s diameter — no guesswork, just perfect compatibility.

Installation and Precautions

1. Easy Installation

• With 15mm - M6 screws (anti - slip head), 1/4 inch screws, and pre - cut M6 holes, setup is straightforward. Attach to your mount, secure your guide scope, and start imaging — no complex tools needed.

2. Key Notes

• Telescope tube diameter: Choose a ring with an inner diameter 1-2mm smaller than your guide scope's diameter (e.g., for an 80mm tube, should you pick one with 78-79mm inner diameter? No! Just refer to the SKU chart and select a ring where the maximum inner diameter is ≤ the tube diameter. The screws can "tighten to compensate" for the gap).
  

• Base screws: Ensure there is a 1/4-inch screw hole (it's a universal interface, compatible with 99% of equatorial mounts).
  

• Manual Measurement: Allow 0 - 2mm error (common in precision machining, doesn’t affect performance).
  

• Monitor Colors: The ring’s red finish may appear slightly different across screens — but rest assured, the actual product’s anodized coating is consistent and durable.
  

• Screw Exposure Reminder: The maximum inner diameter is affected by screw exposure. Follow our setup guide (included) to ensure optimal fit and stability.

Packaging and Services

• Package Includes: 1 x Guide Ring (single ring; pair not included — buy 2 if needed for dual - scope setups).
