The ZWO 30F5 Mini Guide Scope is a compact, high-performance tool designed for astrophotographers seeking precise tracking for long-exposure imaging. With a 30mm aperture and an f/5 focal ratio, this guide scope features a 150mm focal length, an upgrade from its predecessor, the 30F4, providing sharper guide stars and improved tracking accuracy. Its apochromatic (APO) triplet lens system, incorporating extra-low dispersion (ED) glass, minimizes chromatic aberration, delivering pinpoint stars with exceptional clarity. Weighing just 348 grams, its lightweight and streamlined design makes it ideal for portable setups, seamlessly integrating with small refractors or star trackers. The scope’s compatibility with ZWO ASI cameras, via a 1.25” nosepiece or M42x0.75 threaded connection, ensures easy setup for both beginners and seasoned astrophotographers.

The ZWO 30F5 excels in functionality with its non-rotating helical focuser, offering 20mm of focus travel and a locking screw for precise and stable focusing. This feature, combined with its robust construction, ensures consistent performance during extended imaging sessions. The guide scope is optimized for telescopes with focal lengths up to 750mm, making it versatile for guiding, widefield imaging, or even visual observations with an eyepiece. Its adjustable mounting rings and dovetail plate allow for quick installation and alignment with the main telescope.
