ZWO 30mm f/5 Guide Scope

High-precision guiding excellent pinpoint stars
ZWO 30mm F/5 APO Guide Scope features a lightweight and streamlined design. It is independently developed by ZWO to offer high guiding accuracy and stable tracking performance.

Five Major Upgrades to Solve Guiding Challenges
• Upgraded high-precision non-rotating helical focuser with positioning screws to eliminate focus shift
• Extended focal length for sharper guide stars
• Sleek New Look: Mini Telescope Aesthetic
• Upgraded APO optical system for a more regular optical path
• High compatibility and easy installation

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 non-rotating helical focuser Upgraded rigid structure
The 20mm travel non-rotating helical focuser, 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.

After installing the guide scope, unlock the locking screws. Rotate the non-rotating helical focuser clockwise or counterclockwise until the image is clear. Then, tighten the locking screws to secure the focus position.
