Dielectric bevel socket 90° 2" for telescopes, Skywatcher SW-7005

Skywatcher dielectric bevel socket 90° 2" (model SW-7005) is a right-angle 2-inch adapter for telescopes that redirects the optical path by 90 degrees to enable a more comfortable viewing position. The dielectric construction provides a non-conductive interface between the telescope focuser and eyepieces or accessories, preserving optical alignment and allowing easier eye placement for prolonged observation sessions.

Advantages

This dielectric bevel socket offers a stable, 90-degree change of view without introducing electrical conductivity between attached components, which is useful with certain accessories and electronic equipment. The 2-inch diameter accommodates standard 2" eyepieces and many accessories, while the right-angle design improves ergonomics for low or awkward telescope positions. The construction is made to maintain optical alignment and minimize vignetting when used with compatible optical setups.

Suitable for

• Visual observing with 2" eyepieces when a right-angle view is needed
• Astrophotography setups that require reorienting the optical path
• Attaching diagonals, camera adapters or other 2" accessories where a non-conductive interface is preferred
• Use on refractors, reflectors and compound telescopes with 2" focusers or adapters

Key specifications

• Angle: 90° right-angle orientation
• Tube diameter: 2 inches (compatible with 2" eyepieces/accessories)
• Material characteristic: dielectric (non-conductive) construction
• Function: redirects optical path for ergonomic viewing

How to use

Insert the 2" end of the dielectric bevel socket into the telescope focuser or available 2" adapter, securing it according to the focuser's locking mechanism. Insert the eyepiece or accessory into the opposite 2" opening and tighten the retaining screws or thumbscrews to prevent movement. Rotate the socket if necessary to align the viewing orientation, then refocus the telescope to account for the slight change in optical path length introduced by the adapter.

Usage recommendations

Use the dielectric bevel socket with properly sized 2" eyepieces and accessories to avoid excess play. Check and tighten retaining screws before observing to maintain alignment. If using with cameras or sensitive electronics, ensure mechanical support to avoid stress on delicate adapters and minimize flex. Clean optical contact surfaces before assembly to reduce dust and maintain image quality.
