  • Sky Surfer III – Flat base adapter made of ABS

    The Baader Sky Surfer III Flat Base Adapter is a flat ABS base plate for mounting the Sky Surfer III standard finder onto large telescopes. It is already included with the Sky Surfer III; this listing is the single part.

    Universal Flat-Surface Mounting for the Sky Surfer III

    Many finderscopes assume a mounting shoe on a curved optical tube. Baader makes this flat base plate so the Sky Surfer III standard finder can be mounted onto large telescopes.

    Lightweight and Durable ABS Construction

    The adapter is manufactured from Acrylonitrile Butadiene Styrene (ABS), a thermoplastic polymer chosen for its balance of strength and low weight. This ensures the adapter adds minimal weight to your optical assembly, preventing balance issues, especially on smaller telescopes.

    The material is rigid enough to hold the finder securely without flexure, maintaining pointing accuracy, while also being less likely to scratch the finish of your telescope compared to a metal adapter.

  • How do I attach the Sky Surfer III Flat Base Adapter to my telescope?

    Baader does not describe how the single plate is fastened. Its Sky Surfer III manual says to use the screws intended for mounting the finder, and to check screw length on Schmidt-Cassegrain and Maksutov telescopes so the primary mirror is not damaged.

    Is the Sky Surfer III adapter compatible with finders other than the Baader Sky Surfer III?

    This adapter is specifically designed to accept the dovetail foot of the Baader Sky Surfer III. While it may fit other red dot finders that use a Vixen/Synta-style finder foot, compatibility is not guaranteed, and the fit may not be as secure.

    Why is the Sky Surfer III adapter made of ABS instead of aluminum?

    Using ABS plastic offers several advantages for this application. It significantly reduces the weight of the part, which helps maintain the balance of your telescope. It is also corrosion-resistant and less likely to mar the finish of your equipment than a metal part.

    Does the Sky Surfer III Flat Base Adapter come with mounting screws?

    Baader does not list mounting screws with the single plate, so use hardware that suits your telescope.
