Five Major Upgrades to Solve Guiding Challenges
Professional-grade APO Optics Design
ZWO 30mm F/5 Guide Scope uses a professional apochromatic (APO) design with a built-in ED glass, achieving a more regular optical path and effectively reducing the impact of chromatic aberration on stars.
Super Precise Guiding
Compared to the previous generation, the 30mm F/5 guide scope has been upgraded to a 150mm focal length. With the longer focal length, it further improves the guide star quality, providing more stable and accurate guiding performance.
Precise Focusing Knob Upgraded Rigid Structure
The 20mm travel focusing knob, paired with locking screws, allows for accurate focusing and ensures the focused position remains unchanged. The integrated holder further enhances overall rigidity. The quick-release guide scope dovetail plate enables users to rapidly install the guide scope, making it more convenient and easy to use.
