Easy parallel mounting
You mount the William Optics 50mm f/4.0 guidescope parallel to your telescope tube. With ring clamps you can move it slightly to align it precisely. This way, your setup will always start out straight and stable.
Clear image for long exposures
The 50 mm lens captures a lot of light. Your camera can track stars and objects well, keeping your long night photos sharp.
Secure and easy attachment
Thanks to the Rotolock adapter, you clamp your camera or accessories securely. The large, ribbed ring also works with gloves. This way, nothing tilts and you can quickly change setup.
Perfect for astrophotography
With this guidescope, you keep your telescope precisely aligned. Stars stay spot-shaped and your pictures stay sharper longer. Ideal for deep-sky shooting or planetary photography.
