Vai al modulo150 mm achromatic refractor telescope for visual observation and astrophotography
The Sky-Watcher Evostar 150/750 is an achromatic refractor telescope featuring a doublet optical design, a 150 mm aperture and a focal length of 750 mm (f/5). The fast focal ratio makes it a versatile instrument, equally suited to observing low-surface-brightness objects — nebulae, star clusters, galaxies — and to high-resolution lunar and planetary imaging. Compact and relatively lightweight for its aperture class, it is designed to be easily transported to dark-sky observation sites.
Optical performance: deep-sky to planetary observing
With an f/5 focal ratio, the Evostar 150/750 gathers a large amount of light, making it effective for deep-sky observation even under less-than-ideal skies. The 750 mm focal length allows magnifications of up to 300×, enabling high-resolution sessions on the Moon, planets and planetary objects. The anti-reflection coating on the optics improves light transmission, reduces internal reflections and enhances both contrast and image sharpness.
