iOptron designed the green SmartStar Cube-E R80 80mm f/5 GoTo AZ Refractor Telescope as simple yet highly versatile grab-and-go astronomy rig for beginners or advanced amateurs who want to go out for quick observations.

The optical tube has an achromatic doublet lens system that is fully multi-coated to produce bright and sharp high-contrast images with accurate color rendition across a distortion-free field of view. The relatively short focal length produces a fast focal ratio, which makes it ideal for imaging the sun (with proper solar filters installed), moon, and larger planets. With the two included eyepieces offering low and moderate magnifications, plus the addition of an erect-image diagonal, this scope can be used as a traditional terrestrial spotting scope as well as for astronomical observations.

The brains of this system is the GoToNova computer controller. This handheld unit features a 14000+ object database with 256 user-defined objects for your favorite celestial or terrestrial bodies. The easy-to-use menu-driven system displays on a 4-line, 21-character backlit screen. This fully GoTo-capable unit has automatic tracking for fast-moving near-space objects, such as the Moon and planets, and slower moving deep-sky objects like nebulae and galaxies. For setup or manual use, it has five slew speeds starting at 2x and going up to 4°/second. The GoToNova controller is powered by the mount to make use easier and simple while reducing the unit's weight.

Supporting the OTA is the compact Cube-E GoTo Alt-Az mount. This functional, flexible, motorized, and computer-controlled unit is ideal for most stargazing duties, yet sports a compact design that measures a mere 8x5x5" and weighs just 3 pounds. The dual-axis servomotors are built into a small single unit that is easy to carry, even to more remote locations. The unique design eliminates "dead spots," enabling you to point your telescope to any point above the horizon without the risk of blocking the telescope tube at certain points of rotation. This mount comes with a 110 VAC adapter to power it if you're near civilization, but if you're heading off the grid it can run on eight user-supplied AA batteries. An adjustable-height stainless steel tripod is provided to give you a solid and sturdy support system for your night of observing.
