The SVBONY SV106 50 mm Guide Scope is a robust guiding solution designed for accurate autoguiding in astrophotography. Featuring a rigid helical focuser and solid mounting hardware, it delivers stable, repeatable focus and minimal flexure for long-exposure imaging.
Key Features
-
50 mm Guide Scope for Astrophotography
The larger 50 mm aperture gathers more light, making it easier to detect guide stars for accurate tracking. -
Integrated Helical Focuser
Built-in helical focusing mechanism provides smooth, precise focus adjustment while maintaining rigidity and minimising flexure. -
Fine Focus & Locking Control
Knurled focus ring enables precise adjustments, with a locking thumbscrew to secure focus once set. -
Generous Focus Travel
Approximately 8 mm of fine focus travel combined with a 30 mm telescoping drawtube accommodates a wide range of guide cameras. -
Complete Mounting Hardware Included
Supplied with heavy-duty guide rings and a 3.5-inch dovetail mounting bar for secure attachment and accurate alignment.
Rigid Helical Focuser Design
The integrated helical focuser allows precise focus adjustment without introducing tilt or flexure. Nylon-tipped adjustment screws protect the optical tube while enabling accurate alignment with the main telescope.
Secure Camera & Accessory Compatibility
The focuser collar features male T-threads, allowing direct attachment of guide cameras with female T-threads. A copper compression ring ensures secure, damage-free clamping of accessories.
Heavy-Duty Rings & Mounting Bar
The included guide rings and dovetail bar provide a solid, repeatable mounting solution. Once aligned, the SV106 maintains accuracy through long imaging sessions and repeated setups.
Typical Use Cases
- Autoguiding for deep-sky astrophotography
