Get Ready for the Ultra-Cat Telescope Series – Coming Spring 2025!

We are excited to announce the upcoming launch of the UltraCat telescope series by William Optics, set to debut in late spring 2025. This cutting-edge series is designed specifically for medium-format camera users, offering an ultra-large image circle to deliver exceptional performance across a wide range of sensors. With the latest advancements in optical design, the UltraCat series ensures pinpoint star points even in the corners of the image, making it the ideal choice for astrophotographers seeking perfect image quality and precision.

The UltraCat 108 is now available for pre-order, and we encourage you to secure yours before the official release.

Our new telescopes will also feature the newly designed Sensor Tilt Xterminator (STX), an innovative mechanical adjustment system that allows for easy correction of sensor tilt, ensuring perfect alignment for optimal imaging results.

Stay tuned as we expand the UltraCat range with different aperture sizes, bringing the next level of astrophotography performance to your setup.
