## Long description

The DO-GSO 1.25-inch Prismatic 90-Degree Right Angle Socket for Telescopes is an essential optical accessory designed to enhance your viewing comfort during astronomical observations. Built specifically for 1.25-inch telescope eyepieces and accessories, this prismatic right angle socket allows you to observe objects high in the night sky without straining your neck. By redirecting the light path at a convenient 90-degree angle, it ensures ergonomic positioning whether you are viewing planets, stars, or deep-sky objects. Crafted with precision optics, it delivers bright and clear images while fitting standard telescope focusers seamlessly for reliable performance in amateur astronomy.
Advantages
This optical accessory significantly improves observation sessions by providing a comfortable viewing angle, which is particularly beneficial during long viewing periods when targeting objects near the zenith. The integration of precision optics ensures that image brightness and clarity are maintained without noticeable degradation. Its standardized 1.25-inch sizing makes it highly versatile and compatible with a wide range of existing telescope eyepieces and focusers. Additionally, the sturdy construction ensures dependable alignment and durability during regular field use.
Suitable for
Observing celestial objects positioned high in the night sky
Amateur astronomy sessions requiring ergonomic viewing positions
Use with standard 1.25-inch telescope eyepieces and accessories
General stargazing with refractors and catadioptric telescopes
When it may not be suitable
This right angle socket is not suitable for Newtonian reflector telescopes that lack sufficient inward focus travel to accommodate a diagonal or prism without a Barlow lens. It is also not designed for larger 2-inch eyepieces or specialized astrophotography setups that require dedicated correction lenses.
Key specifications
Accessory type: Prismatic 90-degree right angle socket
Barrel size: 1.25-inch
Optics: Precision optical prism
Compatibility: Standard 1.25-inch telescope focusers and eyepieces
How to use
To use the 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, take your 1.25-inch telescope eyepiece and insert it into the receiving end of the right angle socket, tightening its retaining screw to hold it firmly in place. Adjust the telescope focus wheel until the image appears sharp and clear. Always ensure that all retaining screws are securely tightened before starting your observation session to prevent accidental dropping of optical components.
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, requires additional focus travel
Confirm that your existing eyepieces are compatible with 1.25-inch barrels
Always store the right angle socket in a dry, dust-free environment with protective caps attached when not in use. Clean the optical surfaces only with specialized lens cleaning materials to prevent scratching the precision glass.
