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: 45mm
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.
