Whoever coined the phrase "big things come in small packages", would have definitely applied that expression to the OrionStarMax 90 TableTop Maksutov-Cassegrain telescope. This ultra-compact Maksutov-Cassegrain gives surprisingly big views for an instrument of its modest size, making it an elegant first telescope or a pleasantly portable grab-and-go second telescope!

The long, 1250mm focal length (f/13.8) gives the StarMax 90 TableTop telescope some serious magnifying power. The included 25mm and 10mm 1.25" 3-element eyepieces yield powers of 50x and 125x magnification, respectively. The 90mm diameter Maksutov-Cassegrain optical tube collects over 25% more light than its GoScope 80 refractor cousin, and up to 225% more light than a traditional beginner's 60mm refractor telescope. With the advantage of additional aperture, you'll be able to enjoy excellent, detailed views of planetary delights such as lunar landscapes, Saturn's rings and Jupiter's moons through the Orion StarMax 90mm TableTop Maksutov-Cassegrain telescope. As you scan the Milky Way, you'll also be able to pull in sparkling open and globular star clusters, as well as a bright nebula or two.

The optical tube assembly of the Orion StarMax 90mm TableTop Mak-Cass Telescope is attached to a stable table-top swivel base, via a quick-release dovetail mount with adjustable altitude tension. The Maksutov-Cassegrain telescope tube can easily be removed from the table-top base to be mounted on an optional photo tripod. The small swivel base itself can also be mounted on a camera tripod with a 3/8" screw, in case there isn't a table near your preferred observing location.

The StarMax 90mm TableTop Maksutov-Cassegrain comes with a lot of great accessories so you can make the most out of each evening under the stars. An included Orion EZ Finder II red-dot reflex sight lets you aim the 90mm telescope with ease. The Maksutov-Cassegrain's smooth-adjusting internal focuser is a joy to use. The included 90 mirror star diagonal yields bright images and provides a convenient right-angle viewing orientation for comfortable night sky viewing. This compact, yet surprisingly capable, Maksutov-Cassegrain telescope weighs in at just 6.4 lbs. including the diagonal, one eyepiece, and reflex sight device, making it nice and easy for anyone in the family to transport.
