William Optics Guide Scope

The scope is compatible with most standard guide cameras that use a 1.25-inch barrel. Because it features 8mm of focus travel via the threaded barrel, you have enough adjustment range to reach focus with the vast majority of popular CMOS and CCD guide cameras on the market.

The RotoLock system provides a much more secure, centered connection for your camera. Unlike traditional thumbscrews, which can tilt the camera or scratch the barrel, RotoLock uses a rotating collar to apply even pressure, ensuring your camera stays perfectly aligned and vibration-free during long exposures.

Yes, it is designed specifically for that purpose. The 50mm achromatic objective lens provides the high-contrast, sharp star images necessary for your autoguiding software to maintain precise tracking throughout long exposures.

The unit weighs 1.15 lbs. While it is built with a durable, powder-coated finish for longevity, its compact design ensures it won't significantly impact your mount's payload capacity or balance.

The threaded barrel provides 8mm of focus travel, which is sufficient for locking in sharp focus for your guide camera. It is a simple, manual adjustment, so you will want to set your focus once before you begin your imaging session.
