Starizona has developed an astrographic telescope that will deliver the largest, highest quality field of view in its class. With a 70mm diffraction-limited image circle, the Hyperion telescope produces ideal star images over a field large enough to accommodate even the biggest CCD sensors. The Hyperion was engineered to deliver exquisite optical performance and high-quality mechanical design at a cost much less than competing models. The unique optical design allows for very high performance at a fraction of the cost. The Hyperion is the ultimate high-resolution imaging system.

Standard features include a high-precision instrument rotator, integrated telescope control panel, and wireless computer control. The instrument rotator is integrated into the back of the telescope and uses a custom 6-inch brass worm gear and unique stainless-steel bearing system, allowing for a precise and robust design. The telescope control panel, built into the back plate of the telescope, features a digital readout display and control the instrument rotator, cooling fans, dew heaters, and two MicroTouch autofocusers (one for the Hyperion and one for an optional piggyback instrument). All telescope electronic functions are controlled from your computer via a tiny wireless USB box, eliminating the tangle of cables normally associated with running imaging accessories. All features are ASCOM compatible, allowing for automation with popular imaging control software.

The Hyperion uses an innovative Harmer-Wynne optical design. This design provides high performance but is relatively simple to manufacture, allowing us to offer a wealth of features at a competitive price. The Harmer-Wynne design employs a parabolic primary mirror, spherical secondary mirror, and two-element afocal corrector lens located in the primary baffle tube. The result is a flat field free from coma and astigmatism.
