A High Performance Telescope!

With the largest aperture this telescope is the best 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 rest for the more serious skywatchers who want more performance.

Just what's so nifty about this telescope? The answer is best described as "short and sweet."

First, the short. This "ST", or “Short Tube”, version of the SpaceProbe 130 reflector is indeed more compact than the standard model. The telescope’s optical tube measures only 24" long. 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.

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 skywatching and astronomy! It also includes a collimation cap and center-marked primary mirror for easy optical alignment.

The telescope comes on a sturdy and precise EQ-2 equatorial mount with dual setting circles and slow-motion hand controls. After a simple polar-alignment procedure, the EQ-2 mount allows you to easily track celestial objects as they appear to migrate across the night sky, so you can observe them in detail. The adjustable-height aluminum tripod is strong yet lightweight and includes an accessory tray so you can keep eyepieces, flashlights, and other accessories close by while using the reflector telescope.
