SVBONY Compact Ultra-Mini Guide Scope for Auto Guiding Cameras. Compact 4.4"mini guide scope with 30mm f/4 aperture optics. Support sensitive auto guiding cameras for easy guide star acquisition. Features precise helical focus adjustment with thumbscrew lock Ring. Designed for use with the Orion ZWO QYH and so on auto guiding cameras (1.25in or M42 mount interface). Getting this guide scope makes sense for most astrophotographers out there. If you're just starting out, SV165 Mini Guide Scope is easy-to-use and performs well. If you're at the other extreme, using SV165 Mini Guide Scope on your smaller imaging rigs is more practical than trying to mount a larger, more exotic guide scope. If portability is important to you, SV165 Mini Guide Scope's compact size and relatively low weight will cooperate with your requirements. Note:Back focus distance can stretch up to 45mm. Please pay attention to stretch to the end. Focal Length:The objective lens diameter is 30mm. The focal length of the scope is 120mm. F4 aperture optics provides a wide field of view which will help to quickly find the target when performing astronomical observations; 1.25-inch & M42*0.75:The 1.25-inch interface and M42*0.75 male threads allow to connect with SVbony SV305, ZWO, Orion, QYH and other auto guiding cameras; Fully Broadband Multi-Coated:Fully broadband multi-coated optics means the types of coating on all optical surfaces throughout the entire scope. And fully broadband multi-coated optics decreases surface reflectivity therefore allows greater optical through-put across the entire visible light spectrum, increases the light transmission and delivers bright, clear and high-contrast images. Helical Focus Stroke:The 45mm focusing stroke ensures enough focusing range for observing and focus lock ensures a stable focusing. The built-in helical focuser is better for precise focusing of potential guide stars. Ultra-mini Optics:The guide scope is ultra mini and light, and won’t weight your telescope and mount much. High-quality Craftsmanship:High-level CNC machined & Sandblasting Oxidation. |
