Product Description
This “ST”, or “Short Tube”, version of the SpaceProbe 130 reflector is indeed more compact than the standard model. The 130ST reflector optical tube measures 24″ long compared to 33″ on the standard 130. The focal length of the ST’s 130mm (5.1″) primary mirror is 650mm (f/5), yielding a wider field of view and brighter images for a given telescope eyepiece focal length. 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 6×30 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 SpaceProbe 130ST EQ Reflector Telescope Kit comes with extra accessories at a great value! The popular Shorty 2x Barlow doubles the magnification of any 1.25″ eyepiece for a power boost. The included Orion MoonMap 260 is a useful reference map of the Moon’s surface that will help the whole family learn the names and locations of more than 260 craters, mountains, valleys, “seas” and other interesting lunar features you can explore with your telescope. The detailed Orion Telescope Observer’s Guide book highlights over 60 celestial objects to observe in a telescope. Use the included Star Target planisphere to plan your observing sessions year-round! The RedBeam Mini LED light provides dark-friendly red light when you need it under starry skies.

Orion SpaceProbe 130ST EQ Reflector Telescope Kit
Great choice for the more serious beginning stargazer who wants great performance
Our largest aperture SpaceProbe reflector telescope is the niftiest Newtonian reflector on an equatorial mount we’ve seen in a long time. 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.
Optical tube measures 24″ long Focal length is 650mm (f/5) The 130mm aperture primary is a diffraction-limited parabolic mirror
Sirius Plossl Eyepieces
The included 1.25″ Orion 25mm Sirius Plossl eyepiece provides a 26-power view when used with the SpaceProbe 130ST reflector telescope. When you’re ready to study objects with more magnification, use the included 10mm Sirius Plossl eyepiece. When inserted into the SpaceProbe 130ST reflector telescope, the 10mm Plossl provides a powerful, 65x view with a 52° apparent field of view, so you can inspect interesting objects more closely.
Orion Shorty 2x Barlow Lens
A 2-power (2x) Barlow lens is an extremely versatile telescope accessory that doubles the magnification of any eyepiece installed. Using the included Shorty 2x Barlow with the 10mm eyepiece in the SpaceProbe 130ST reflector bumps its viewing power from 65x to 130x, and boosts the 25mm eyepiece’s magnification from 26x to 132x when used with the 130mm telescope. What’s more, you can use the compact Shorty 2x Barlow with any other 1.25″ eyepieces you already have, or any you purchase in the future.
