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
• Medium to long focal-length imaging systems
• Setups requiring rigid, low-flexure guiding
• Permanent or semi-permanent observatory rigs
