Key Advantages
- Achromatic Objective: A special two-lens combination effectively corrects most color aberrations for superior image quality compared to standard Fraunhofer refractors.
- 1:10 Aperture Ratio: The f/10 focal ratio provides an additional positive effect on image sharpness and clarity.
- AZ-3 Altazimuth Mount: A practical, easy-to-use mount that provides excellent stability for various optical instruments.
- Fine Adjustment Controls: Flexible slow-motion controls on both axes allow for smooth tracking even at high magnifications.
- Wide Viewing Range: Adjustable vertical angle from 50 to 90 degrees allows for viewing from the horizon to nearly the zenith.
Product Description
The AC 90/900 optics are equipped with an achromatic objective that minimizes disturbing color irregularities. This makes it a perfect choice for observing bright celestial bodies such as the Moon and planets without the purple fringing often found in lower-quality telescopes. With its 90mm aperture, it gathers enough light to reveal intricate details within our solar system and the brightest deep-sky objects.
The Sky-Watcher AZ-3 mount is highly versatile, supporting telescopes or spotting scopes up to a maximum weight of 5kg. It features a horizontal quick adjustment with a locking screw and a vertical rapid adjustment with a slipper clutch. The 360° panning capability makes it equally suited for astronomical tracking and terrestrial scouting. The included aluminium tripod is infinitely adjustable in height, ensuring a comfortable observing position for every user. The entire system remains lightweight and portable, making it an ideal companion for field trips.
