SVBONY SV221 1.25 inch 45-Degree Correct-Image Prism Diagonal for Refractor Telescopes

The SV221 diagonal mirror features a 45-degree design to reflect the telescope's light path and provide a more comfortable viewing angle, suitable for observing overhead objects. It corrects the image, delivering an upright view without inversion. The SV221 diagonal mirror has a 1.25-inch interface and 28.5x0.6 thread size, allowing it to connect to 1.25-inch astronomical telescopes and filters for a better observation experience.

The diagonal mirror is compatible with standard 1.25-inch telescope accessories, such as eyepieces and filters, protecting the eyepieces. It has a brass pressure ring design that provides a uniform pressure receiving area when holding the eyepiece, ensuring the accessories are firmly fixed without damaging the eyepieces.

The SV221 diagonal mirror features large thumb screws, allowing for convenient twisting during use. The operation is more portable, and it can be easily fixed even when wearing gloves in winter. This diagonal mirror can be used to observe the moon and planets, suitable for a variety of scenarios.

Specification-wise, the SV221 diagonal mirror has a 1.25-inch barrel on the lens side, a 1.25-inch clamp on the inner connection, and a multi-coated (MC) coating. It provides an erect image orientation and has an optical length of approximately 86mm. The clamping system uses screw clamps, and the deflection angle is 45 degrees. The clear aperture is 19mm, and the material is a combination of plastic and metal, with a net weight of 79g/2.78oz.

The SV221 diagonal mirror offers clear views with its 45-degree correct-image prism design, providing sharp observations. The main mirror housing is made of precision-molded ABS plastic, while the two end barrels are precision-machined from aluminum, ensuring a sturdy and innovative design.

Equipped with brass lock screw and compression rings, the diagonal mirror provides a precise connection and protects against scratches and damages. It supports the use of 1.25-inch filters, enhancing the versatility of observations. The multi-coating on the surfaces ensures a comfortable viewing experience, and the dustproof design with a cover helps keep the lens clean.

The SV221 diagonal mirror is designed for refractor telescopes and some catadioptric telescopes like Schmidt-Cassegrain and Maksutov-Cassegrain, but it is not compatible with Newtonian/Dob reflector telescopes. Its screw clamping system allows for secure and easy usage, making it a versatile and convenient accessory for various astronomical observations.
