SVBONY SV198 50mm Finder Scope with Dual Helical Focuser Bundle

The 50mm Aperture Guide Scope features a versatile 50mm aperture and a built-in Dual helical focuser. The Helical Focuser Collar ensures that attached auto guider devices do not rotate during focus adjustments. This guide scope can also be used as a right-angle correct-image optical finder scope (Eyepieces and Prism Diagonal sold separately).

For those who find it inconvenient to carry the Optical Tube Assembly (OTA), the SV211 handle bar is the solution to their travel problems. This handle bar is suitable for close handling and protects the OTA from damage. Additionally, it can be used as a general dovetail, making it compatible with all SVBONY guide scopes and finder scopes, especially the SV198 guide scopes.

The SV188P dielectric diagonal features dielectric coatings that provide 99% reflectivity, an M28.5x0.6 filter thread that can connect with 1.25-inch filters directly, and a built-in brass ring to prevent the accessories barrel from being scratched. The machined and anodized aluminum housing makes the SV188P dielectric diagonal durable and uniform.

The SV211 CNC handle bar adopts M6 mounting screw holes and has a unified interface type, making it highly adaptable. The CNC metal handle provides a guide scope and finder scope mounting platform for easy installation of accessories. The full CNC integrated finishing and anodized aluminum construction ensure a long service life.

The 50mm aperture and large diameter objective lens of the guide scope collect more light, resulting in a clearer view of the target in the field of view. This makes it convenient to find a target in the sky. The comfortable and convenient carrying handle is suitable for the OTA SV503 (70 F6; 80F7) and SV550 (80F6), and the adjustable position of the handle improves the safety factor of the product installation process.

The dielectric coatings on the diagonal provide a super flat mirror with over 99% reflective surface, which is beneficial for astronomical viewing. The built-in brass ring and thumbscrew accessories prevent the eyepiece from rotating during adjustments, ensuring a secure and effortless fit without scratching the eyepiece barrels.

In conclusion, the 50mm Aperture Guide Scope, SV211 handle bar, and SV188P dielectric diagonal offer a comprehensive solution for amateur astronomers. The versatility, adaptability, and durability of these products make them an excellent choice for enhancing the viewing experience and addressing common challenges faced by users.
