Sky-Watcher AC 90/900 EvoStar EQ-2 Telescope Solarsystemscope SET

AC 90/900 Optics:

Featuring an achromatic objective, the AC 90/900 optics employ a unique combination of two lenses within the objective to effectively correct most color aberrations. This design innovation minimizes the typical irregularities encountered with standard Fraunhofer refractors, ensuring a clearer viewing experience. With an aperture ratio of 1:10, this optics system delivers additional benefits, enhancing your observation sessions.

The EQ-2 Mount:

The EQ-2 mount offers a parallactic mounting system, providing precise alignment with the Pole Star for accurate tracking. Adjust the pole height and geographic amplitude for each observing location. Fine movements along the right ascension and declination axes allow for precise object tracking. The aluminum tripod features three extendable legs, offering adjustable height from 71cm to 121cm, making it suitable for observers of all ages, including children.
