All-metal or high-strength engineering plastic construction for durability. Lenses have anti-reflective coatings for better light transmission. Some models include a dew shield.
This 9×50mm right angle correct-image finder scope OTA is equipped with built-in crosshair, featuring fully upright imaging for fast celestial alignment and auxiliary positioning of main telescopes.
With clamping guiding rings, it can be stably mounted on telescope tubes with firm locking, preventing displacement and looseness during long-time outdoor observation.
The right-angle optical structure optimizes viewing posture without excessive bending, which is suitable for prolonged outdoor astronomical observation.
High-transmittance optical elements provide a wide and transparent field of view with good celestial recognition for smoother star finding.
It adopts universal mounting design to fit most conventional astronomical telescopes. The sturdy body supports simple installation and adjustment.
Standard dovetail base compatible with finder scope mounts on most telescope tubes for quick attachment. Adjustment screws enable easy alignment with main scope.

Most telescopes come with a small, straight-through finder telescope. But many astronomers prefer the use of larger, right-angle finders that offer many more advantages. With a 50mm finder, you can hunt down fainter objects that you would not see in smaller 24mm or 30mm stock finders. "Correct Image" finders present a view that matches the orientation of the sky or the orientation of the stars in star charts. And, perhaps most importantly, your back and neck will thank you for using a "Right-Angle" finder and no longer subjecting them to various contortions at the telescope.
