The Orion Apex 127mm Maksutov Cassegrain Telescope boasts big 127mm (5") diameter optics but in a tube that's a fraction of the length (just 15" long) and weight (8.6 lbs) of a Newtonian reflector or refractor of similar aperture and focal length. It's high-performance optics gives the Apex 127 Mak such outstanding image quality and such an incredible range of uses for the demanding observer. It gulps in 55% more light through its multi-coated, 5" meniscus lens than that of a 4" scope, putting it in the big leagues for astronomical observation and advanced nature study.
And its long 1540mm (f/12.1) focal length provides 62x magnification with the included 25mm Sirius Plossl eyepiece (1.25") and lets you push the power up to 250x with optional eyepieces! Bright views of star clusters and nebulas at low power, stunning lunar and planetary detail at higher power. And as a daytime spotting scope, no instrument is more capable, especially in low-light conditions. It couples quickly to any sturdy equatorial mount or photo-style tripod (Orion recommends Paragon-Plus XHD tripod, #5360) thanks to a built-in 1/4"-20 adapter plate. Mounting and disassembly are a snap. Quality is evident not only in the optics, but also in the black-anodized aluminum front and rear castings, the smooth-turning focus knob and the extruded aluminum tube, with a classy, metallic-burgundy finish.
The 6x26 achromatic, correct-image finder scope features a quick-release aluminum bracket with a dovetail base and two-screw X-Y alignment. The 25mm Sirius Plossl eyepiece slips into a 45° correct-image prism diagonal, also included. The T-threads on the eyepiece adapter allows attachment of a 35mm camera body (with optional T-ring) to the scope for telephoto photography. It also include a fully padded, nylon/polyester carrying case, which has plenty of room for additional accessories in the zippered side pockets.
