Visit Sky-Watcher EVOSTAR 90 EQ3-2 is a high-quality achromatic refractor designed for outstanding optical performance and tracking accuracy. Designed for demanding novice astronomers and intermediate users alike, it combines high-performance optics with a stable, upgradeable equatorial mount. This instrument is ideal for exploring the Moon, planets and solar system objects in detail, with sharp, high-contrast images.
Thanks to its 90 mm diameter, This telescope captures enough light to provide bright, detailed observations. Its focal length of 900 mm and its focal ratio of f/10 make it ideally suited to high-magnification observation, guaranteeing excellent resolution and high contrast.
The Sky-Watcher EVOSTAR 90 is based on a classic achromatic doublet optical design. This system effectively reduces chromatic aberrations while maintaining a sharp, faithful image. This proven design ensures ideal image quality for detailed observations.
The lens features Multi-Coated, The result is brighter images and greater contrast. The result is brighter images and greater contrast, particularly appreciated when observing lunar craters or planetary details.
Thanks to its performance close to the diffraction limit, this telescope offers excellent optical precision, enabling its full potential to be exploited when observing at high magnification.
The Sky-Watcher EVOSTAR 90 EQ3-2 is supplied with two eyepieces of 25 mm and 10 mm, which can achieve magnifications of x36, x72, x90 and x180 thanks to the included x2 Barlow lens. Theoretical maximum capacity x180, perfectly suited to detailed observation of the Moon, planets and double stars.
Its f/10 focal ratio ensures excellent detail at high magnification, with a stable, high-contrast, well-defined image. This makes it ideal for studying the solar system.
The bezel is mounted on a EQ3-2 Deluxe equatorial mount, With its integrated polar finder mount, it offers superior tracking accuracy to lighter mounts. Once correctly aligned, thanks to its integrated polar finder mount, it enables easy tracking of celestial objects by compensating for the Earth's rotation.
Visit slow-motion controls allow precise adjustment on both axes, making it easy to track objects in the sky. This mount is particularly well-suited to prolonged observations, and provides an excellent basis for an evolution towards astrophotography.
The sturdy aluminum tripod ensures good stability, limiting vibrations for optimal viewing comfort. The integrated accessory tray makes it easy to organize your equipment during your sessions.
The Sky-Watcher EVOSTAR 90 EQ3-2 comes with a complete set of accessories for immediate use. The 1.25” angled return” ensures comfortable viewing, especially when the telescope is oriented towards the zenith.
The included x2 Barlow lens is equipped with a camera adapter, This feature is an excellent introduction to astrophotography. This feature offers an excellent introduction to astrophotography.
The researcher 6×30 makes it easy to locate celestial objects, enabling you to set up your observations quickly and efficiently.
Designed to offer a seamless user experience, the Sky-Watcher EVOSTAR 90 EQ3-2 is relatively simple to set up and operate. The equatorial mount requires a slight learning curve, but in return offers superior precision and comfort when tracking celestial objects.
This telescope is an excellent choice for users wishing to progress in astronomy while benefiting from a reliable, high-performance instrument.
