William Optics 90° 1.25″ Zenith prism Cat 51 WIFD

Look relaxed, without neck pain
The William Optics 90° zenith prism lets you look up comfortably, even during long sessions. The prism deflects light 90°, so you don't have to stretch or twist. You just look straight into the eyepiece and stay relaxed.

Natural image, ideal for nature and Moon
The prism straightens out the inverted telescope image. That makes it perfect for birds, landscape and anything you want to view during the day. You also see the Moon as you see it outside. No strange rotations. No hassle with orientation. You recognize craters and valleys at a glance.

Clear and sharp thanks to premium glass
BaK-4 glass and a dielectric coating keep your image clear. Reflections stay low, contrast stays high. This means you see fine details better. Stars stay sharp. The Moon shows more structure. Everything feels just a little nicer and quieter.

Fits effortlessly into your setup
With the 1.25″ connection, you can easily click the prism into many telescopes. It works perfectly with the William Optics RedCat 51 WIFD. The ring clamp holds your eyepiece securely without damaging it.
The included 2″ / 1.25″ adapter makes changing fast and easy.

Compact, sturdy and ready for outdoor use
The aluminum house feels solid and is built for years of use under the stars as well as in nature. You easily take it with you and put it back in just as quickly.
