10000015 : Orion 130ST EQ Telescope
Product #: 10000015
Designed for the serious beginning or intermediate stargazer 130mm (5.1") aperture and 650mm focal length for a wider field of view and brighter images Includes sturdy tripod and equatorial mount for hands-free celestial tracking Includes FREE Starry Night astronomy software One-year limited warranty.
The SpaceProbe 130ST EQ is a rich-field Newtonian reflector with a tube only 24" long compared to the 33" tube length of the standard 130 EQ. The focal length of the ST's 130mm (5.1") primary mirror is 650mm (f/5), producing a wider field of view and brighter images for a given eyepiece focal length. The diffraction-limited parabolic primary mirror is the same type used on much larger reflectors costing substantially more. On a short-focal-length design like this one, a parabolic mirror is a must for delivering sharp, detailed images. This scope package includes an EQ-2 equatorial mount with dual setting circles and manual slow-motion controls, adjustable aluminum tripod with accessory tray, two Plossl eyepieces (25mm and 10mm), and a 6x30 achromatic finder scope.
Orions largest aperture SpaceProbe reflector telescope is a Newtonian reflector on an equatorial mount. The Orion SpaceProbe 130ST EQ Reflector Telescope is a step up from the standard SpaceProbe 130 EQ for the more serious beginning or intermediate stargazer who wants additional performance, particularly for targeting deep-sky objects. This ST, or Short Tube, version of the SpaceProbe 130 reflector is indeed more compact than the standard model. The 130ST reflector telescope's optical tube measures 24 inches long compared to 33 inches on the standard 130. The focal length of the ST's 130mm (5.1inch) primary mirror is 650mm (f/5), yielding a wider field of view and brighter images for a given telescope eyepiece focal length. That brings us to sweet. The 130mm aperture primary is a diffraction-limited parabolic mirror, the same type used on much larger reflector telescopes costing many times as much. On a short-focal-length design like this one, a parabolic mirror is a must for focusing incoming light to a point and delivering sharp, detailed images. Moreover, the secondary mirror is held in an advanced holder with thin 0.5mm metal vanes, to reduce diffraction spikes and light loss. These features combined with the included 25mm (26x power) and 10mm (65x power) Sirius Plossl telescope eyepieces and quick-release 6x30 achromatic finder scope make this one sweet optical system for astronomy! The SpaceProbe 130ST EQ reflector telescope also includes a collimation cap and center-marked primary mirror for easy optical alignment. The Orion SpaceProbe 130ST telescope comes on a sturdy and precise EQ-2 equatorial mount with dual setting circles and slow-motion hand controls.
