The SVBONY SV165 30 mm f/4 Mini Guide Scope is an ultra-compact guiding solution designed for lightweight astrophotography setups. Its small form factor and fast optics make it ideal for portable rigs, star trackers, and short-focal-length imaging systems where minimal added weight is essential.
Key Features
-
Ultra-Compact 30 mm Guide Scope
Extremely lightweight design minimises load on small mounts and star trackers while still providing reliable guiding. -
Fast f/4 Optical System
The fast focal ratio delivers bright guide stars, improving sensitivity when paired with modern guide cameras. -
Fully Multi-Coated Optics
Broadband multi-coated lenses improve light transmission and contrast for consistent guiding performance. -
Helical Fine Focuser
Smooth helical focusing allows accurate focus adjustment and repeatability during imaging sessions. -
Lightweight Aluminium Construction
Durable metal body provides rigidity while remaining suitable for travel-friendly astrophotography setups.
Designed for Lightweight Astrophotography Rigs
The 30 mm aperture and compact size make this guide scope especially well suited to wide-field refractors, camera-lens imaging, and star-tracker setups where larger guide scopes would be impractical.
Optical Performance & Focal Length
With an approximate focal length of 120 mm, the SV165 offers a wide guiding field that makes locating suitable guide stars easier, particularly when working with short-focal-length imaging systems.
Helical Focusing & Camera Compatibility
The helical focuser provides smooth, precise focus control for small guide cameras. Its simple design reduces flexure and helps maintain focus throughout long imaging sessions.
Typical Use Cases
- Star trackers and ultra-portable mounts
- Wide-field refractor astrophotography
- Camera-lens deep-sky imaging
- Secondary guide scope for lightweight setups
