Acuter is a world-class brand of innovative, high-quality products for amateur astronomy and educational use.

HIGH QUALITY VERSATILE INSTRUMENT FOR ASTRONOMY, TARGET SPOTTING, NATURE OBSERVING & PHOTOGRAPHY

The new ACUTER VOYAGER MAK90-FAST is a high quality and powerful Maksutov-Cassegrain telescope with a 90mm aperture. This compact and easily transportable telescope is ideal for observing and learning about the night sky. Ideal for the observation of double-stars, and the surface detail of the Moon and bright planets. Since the image is upright and fully corrected, you can also observe nature during the daytime. You can also capture images using your own smartphone using the included smartphone camera adapter. The long focal length optical system is broadband multi-coated to maximize contrast and image sharpness.

The FAST designation in the name is due to the revolutionary patent-pending friction drive focuser with focus distance indicator. Instead of having a focusing knob that is twisted, which is common on Maksutov-Cassegrain telescopes, it is equipped with a friction driven focuser with dual focus knobs (patent pending design) which moves the primary mirror to achieve focus. In addition there is an immensely helpful focus distance indicator scale that shows the position the focuser needs to be to view objects at distances of 8m, 17m and infinity. This focuser design truly enables FAST focusing to be achieved with the minimum of fuss.

The telescope is compact and convenient enough to take it with you on your next vacation trip.

The set consists of a superb 90mm Maksutov-Cassegrain telescope OTA with 1170mm focal length, a 20mm 58.5x magnifying eyepiece with a wide 70 degree apparent field of view, an optical 6x21 erect image finderscope, a particularly high-quality, phase-corrected 90° image-erecting roof prism diagonal, a smartphone camera adaptor, to keep a photographic record of your observations, and a carrying case. The telescope can be expanded as required with optionally available standard 1.25 "telescope eyepieces to increase the range of magnifications.

The Maksutov telescope is named after Dmitri Maksutov (1896-1964), a Russian optician and astronomer who introduced this telescope design in 1941.
