Skywatcher AC 90/900 EvoStar EQ-2 Telescope

Description

Track the rings of Saturn and cloud belts of Jupiter along celestial coordinates with the Skywatcher AC 90/900 EvoStar EQ-2 Telescope manual equatorial refractor system. Designed with an f/10.0 focal ratio, this 90mm (3.54 in) aperture telescope features a 900mm focal length, delivering 1.29 arcseconds Dawes resolving power and reaching magnitude 12.5 for entry-level planetary observation.

The Skywatcher AC 90/900 EvoStar EQ-2 Telescope features an air-spaced Fraunhofer achromatic doublet objective with multi-coated anti-reflection crown and flint optical glass elements. Its 910mm aluminum tube features internal stray light baffles, an unobstructed 0% central profile, and a 1.25-inch rack-and-pinion focuser with integrated T-2 camera threads. Mounted on an EQ-2 manual German equatorial mount with an aluminum tripod, the 2.48 kg OTA ensures steady polar tracking across solar system targets.

Key Features of Skywatcher AC 90/900 EvoStar EQ-2 Telescope

Built for entry-level equatorial tracking and planetary exploration, this 90mm Sky-Watcher EvoStar refractor telescope pairs an f/10.0 Fraunhofer doublet with an EQ-2 mount. Its manual right-ascension slow-motion controls and 6×30 finderscope provide sharp, comfortable views of the Moon and bright planets.

Fraunhofer Doublet Optics & Pure Color Fidelity

The 900mm focal length eliminates chromatic edge fringing on bright targets, delivering sharp views of lunar rilles and planetary disks. Featuring zero central obstruction, this Sky-Watcher EvoStar refractor supports visual magnifications from 12.9x up to 180x.

EQ-2 Equatorial Mount & Manual RA/Dec Controls

Following celestial targets at high magnification requires polar alignment tracking. The Sky-Watcher EvoStar 90 EQ-2 features an equatorial mount head equipped with slow-motion control cables that allow stargazers to follow objects along right ascension smoothly. Paired with an aluminum tripod and counterweight, it provides a stable platform for planetary observation.

• EQ-2 manual German equatorial mount with counterweight for smooth polar tracking
• 1.25-inch 90-degree star diagonal paired with Super 25mm and 10mm eyepieces
• 6×30 optical finderscope for accurate manual target acquisition in the night sky
