Description
50mm f/4.1 Guidescope (Gen II) — 205mm Compact Autoguiding Scope
The Starfield 50mm f/4.1 Guidescope (Gen II) is a redesigned, compact autoguiding scope built for reliable tracking with minimal added bulk. With a 205mm focal length and bright wide-field optics, it keeps more potential guide stars in view—so you spend less time hunting and more time capturing clean, well-tracked data.
Designed for: compact imaging rigs, portable setups, and any system where rigid guiding and quick guide-star acquisition matter.
Key Features
Fully Multi-Coated Doublet Optics with High Contrast
The fully multi-coated doublet delivers sharp, contrasty stars. Matte-black internal baffling helps suppress reflections, while the built-in dew shield reduces stray light and helps protect the optics from condensation during long sessions.
Non-Rotating Helical Focuser for Stable Framing
A heavy-duty, non-rotating helical focuser helps keep your guide camera from spinning while you focus—making framing and calibration easier. Locking screws hold focus securely for dependable guiding performance.
All-Metal Construction and Universal Mount Fit
High-quality all-metal construction helps keep the system rigid and field-ready. The guidescope is designed to fit Celestron, Sky-Watcher, Vixen, and synta-style saddles and includes a universal finder shoe for flexible mounting.

FAQ
Why does “non-rotating” focusing matter?
If the camera rotates while you focus, it can change framing and complicate calibration. A non-rotating helical focuser keeps the camera orientation stable.
Will this work on my mount or telescope?
The guidescope is designed to fit common Celestron, Sky-Watcher, Vixen, and Synta-style saddles and includes a universal finder shoe for flexible mounting.
What makes this better for finding guide stars?
A bright, wide field increases the chances that usable guide stars are in-frame—helping you lock on faster and guide more reliably.
