DO-GSO 1.25-inch Prismatic 90-Degree Right Angle Socket for Telescopes

The DO-GSO 1.25-inch Prismatic 90-Degree Right Angle Socket for Telescopes is an essential optical accessory designed to enhance your astronomical viewing experience. By bending the light path at a convenient 90-degree angle, this device allows for much more comfortable viewing positions when observing objects high in the night sky. Built to accommodate standard 1.25-inch eyepieces and accessories, it ensures dependable performance and clear image transmission for stargazing enthusiasts.

Advantages

Using this 90-degree right angle socket significantly reduces neck and back strain during long observation sessions, especially when your telescope is pointed near the zenith. The prismatic design delivers bright and correctly oriented views suitable for general stargazing. Its standard 1.25-inch sizing makes it highly versatile and compatible with a wide range of existing telescope eyepieces and accessories, allowing you to easily integrate it into your current optical setup without additional adapters.

Suitable for

• Observing celestial objects high in the night sky with standard 1.25-inch eyepieces
• General astronomical viewing sessions requiring a comfortable body posture
• Refractor and catadioptric telescope setups utilizing 1.25-inch focusers

When it may not be suitable, this accessory is generally not intended for Newtonian reflector telescopes, as they often lack the necessary inward focus travel to reach focus with a standard star diagonal. Additionally, users seeking specialized erecting prisms for terrestrial daytime viewing or advanced high-magnification planetary imaging may require different optical configurations.

Key specifications

• Accessory type: 90-degree prismatic right angle socket
• Barrel size: 1.25 inches
• Design: Prismatic light path bending
• Compatibility: Standard 1.25-inch telescope eyepieces and focusers

To use the DO-GSO 1.25-inch Prismatic 90-Degree Right Angle Socket, first remove any dust caps from both ends of the unit. Insert the 1.25-inch barrel of the socket directly into the telescope focuser and secure it using the thumbscrews provided on your telescope. Next, insert your chosen 1.25-inch eyepiece into the upper socket and tighten the retaining screw gently. Adjust the focus wheel on your telescope until the celestial image appears sharp and clear.

What to consider before purchase

• Verify that your telescope uses a standard 1.25-inch focuser size
• Check if your telescope type, such as a Newtonian reflector, has sufficient backfocus capabilities
• Confirm whether a prismatic design meets your specific astronomical observation preferences

Usage recommendations: Always store the optical socket in a dry, dust-free environment with protective caps attached when not in use. Clean the optical glass surfaces only with specialized lens cleaning supplies to prevent scratching and maintain optimal image transmission.
