Meade Instruments' compact StarNavigator NG 90mm f/13.9 GoTo Maksutov-Cassegrain Telescope is ideal for users who want a portable yet powerful observation platform that is able to achieve high magnifications for detailed views of the moon and planets as well as the ability to reach out past our solar system to observe brighter deep-sky objects such as nebulae and galaxies. The compact and powerful Maksutov design uses a front corrector plate with a convex meniscus lens to correct off-axis aberrations, like comas, and chromatic aberration to produce images with true color rendition. The nature of the lens results in a smaller secondary mirror - limiting obstruction and increasing contrast, while eliminating the need for periodic collimation. This optical path results in a slower focal ratio and narrower field of view versus a similar Schmidt-Cassegrain variant, but the optical benefits makes this an ideal scope for all types of celestial observations.

Driving the dual-axis DC servo motors in the single-arm fork mount is the AudioStar hand controller. This update to their iconic AutoStar enables quick and easy set up and alignment to get you observing faster, while offering guided tours and audio commentary on 500 of its over 30,000 objects in the internal database. For those who want to use it for astrophotography, an internal mirror flips down to direct the light path straight back for prime-focus photography using a DSLR camera body and optional adapters. An equatorial tilt plate is integrated into the tripod, which allows for proper polar alignment and single-axis tracking for smoother and more precise tracking as required by long-exposure photography.
