The Baader 1.25" 90° Prismatic Right Angle Socket is a precision-engineered optical accessory designed to enhance the viewing experience for telescope users. Featuring a 32mm clear aperture, this prism diagonal allows for efficient light transmission, ensuring that celestial objects appear bright and sharp. The 90-degree viewing angle is specifically designed to provide a more ergonomic posture during long observation sessions, allowing users to view the sky comfortably without straining their neck or back.
Advantages
This prismatic diagonal offers superior image orientation compared to standard mirror diagonals, providing a crisp and high-contrast view of the night sky. Its robust construction ensures long-term durability and stability, making it a reliable component for both amateur astronomers and professional setups. The 1.25-inch standard sizing ensures broad compatibility with a wide range of telescopes and eyepieces, while the high-quality glass material minimizes light scattering and maintains optical integrity throughout the observation.
Suitable for
- Visual astronomical observations of the Moon and planets
- Deep-sky object viewing with standard 1.25-inch eyepieces
- Refractor and catadioptric telescope setups
- Long-duration stargazing sessions requiring ergonomic viewing angles
When it may not be suitable
This prism diagonal is not recommended for use with fast Newtonian telescopes, as it may introduce optical aberrations. It is also not intended for terrestrial photography or applications requiring a fully corrected erect image, as the prism provides a mirror-reversed view.
Key specifications
- Barrel size: 1.25 inches
- Clear aperture: 32mm
- Viewing angle: 90 degrees
- Optical design: Prismatic
How to use
To use the Baader 1.25" 90° Prismatic Right Angle Socket, simply insert the 1.25-inch barrel into the focuser of your telescope and secure it using the locking screws. Once firmly in place, insert your preferred 1.25-inch eyepiece into the top socket of the diagonal. Adjust the telescope's focus until the image appears sharp. Ensure that the diagonal is oriented in a way that allows for the most comfortable viewing position for your specific setup.
What to consider before purchase
- Verify that your telescope focuser accepts 1.25-inch accessories
- Ensure your telescope focal ratio is compatible with prism diagonals
- Consider the orientation of the image, as this unit provides a mirror-reversed view
Usage recommendations
Always keep the optical surfaces clean by using a specialized lens cleaning kit to prevent dust and smudges from affecting image quality. Store the diagonal in a dry, dust-free environment when not in use to maintain the integrity of the prism coatings.
