Product Description & Reviews
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 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 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.

Some of the most picturesque celestial objects are too large to fit in the field of view of an imaging refractor and camera. What's more, most objects in deep space are very faint and therefore challenging to image without taking very long exposures, increasing the potential for error. Our new Orion 0.8x Focal Reducer for Refractors addresses these obstacles by increasing your refractor telescope's field of view while reducing the effective focal length by a factor of 0.8x, thereby providing a s

Focusing a telescope by hand can cause the image to shake or even move completely out of the field of view, especially at high magnifications. But with the AccuFocus electronic focuser, those annoyances are a thing of the past. Using the pushbutton hand controller you get smooth, precise focusing, without vibration. Choose any speed from coarse to very fine. The DC motor installs easily and works with many Orion telescopes. It's powered by one 9-volt battery (included) in the hand controller. Br
