Orion StarMax 90mm TableTop Maksutov-Cassegrain Telescope
Whoever coined the phrase "big things come in small packages", would have definitely applied that expression to our new StarMax 90 TableTop Telescope. This ultra-compact Maksutov-Cassegrain (Mak-Cass) gives surprisingly big views for an instrument of its modest size, making it an elegant first telescope or a great grab-and-go second telescope! The long, 1250mm (f/13.8) focal length gives the StarMax 90 TableTop some serious magnifying power - the included 25mm and 10mm 1.25" eyepieces yield powers of 50x and 125x, respectively. It collects over 25% more light than its GoScope 80 cousin, and up to 225% more light than a 60mm refractor telescope. So you''l be able to enjoy planetary delights such as lunar landscapes, Saturn's rings and Jupiter's moons. As you scan the Milky Way, you''l also be able to pull in some open and globular star clusters, as well as a nebula or two. The tube assembly of the StarMax 90mm TableTop Mak-Cass Telescope is attached to a stable swivel base, via a quick-release dovetail mount with adjustable altitude tension. The tube can easily be removed from the base and mounted on an optional photo tripod. The small swivel base itself can also be mounted on a camera tripod with a 3/8" screw. A red-dot view finder, internal focuser (which moves the primary lens back and forth) and included 90-degree correct image diagonal round out the features of this compact, yet surprisingly capable, Mak-Cass telescope.
