You mount the William Optics AC 50/200 guidescope parallel to your telescope tube. This way you follow stars and objects automatically. With a camera attached to the 1.25-inch connection, you can make long exposures without stars blurring.
Large field of view
The wide 5.7° field of view helps you align quickly and accurately. You see more of the sky at once, which makes aiming easier.
Firm and easy attachment
The RotoLock clamp keeps your camera or accessories securely centered. It is easy to operate by hand, even with gloves. This way, nothing tilts while shooting.
Compact and lightweight
With a tube weight of 460 grams and a length of 265 mm, this guidescope is easy to mount and transport. Ideal for mobile setups or smaller telescopes.
