Svbony SV198 50mm Guide Scope

The SV198 50mm Guide Scope is the simple, lightweight way to tighten up your tracking and stop throwing away subs to star trails. It’s compact enough to ride on almost any imaging rig without turning your payload into a brick, but still gives you a bright 50mm aperture view for reliable guide star pickup—especially helpful when you’re pushing longer exposures.

• Lightweight, compact design that won’t punish your mount’s payload capacity
• 50mm aperture delivers bright, clear star images for confident guiding in low-light skies
• Built for accurate star tracking—helps reduce drift and minimize star trails in long exposures
• A great match for long-exposure astrophotography (DSO imaging, narrowband, longer focal lengths)
• Rugged, outdoor-ready construction designed for reliable performance in real field conditions
• Easy installation on most telescopes with quick alignment adjustments for smooth setup
• Ideal “set it and forget it” guiding upgrade for imaging rigs that need steadier tracking without extra complexity
