The newest addition to our SpaceProbe line of scopes is the niftiest equatorial reflector we've seen in a long time. It's a step up from the SpaceProbe 130 for the more serious beginning or intermediate stargazer who wants additional performance, particularly for targeting deep-sky objects.
Just what's so nifty about the Orion SpaceProbe 130ST Equatorial Reflector Telescope? The answer is "short and sweet."
First, the short. This "ST" version of the SpaceProbe 130 is indeed more compact than the standard model. The ST's optical tube measures 24-inches long compared to 33-inches on the standard 130. The focal length of the ST's 130 mm (5.1-inch) primary mirror is 650 mm (f/5), yielding a wider field of view and brighter images for a given telescope eyepiece focal length. That brings us to sweet. The 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 0.5 mm metal vanes, to reduce diffraction spikes and light loss. These features combined with the included 25 mm (26x) and 10 mm (65x) Sirius Plossl telescope eyepieces and quick-release 6 x 30 achromatic finder telescope make this one sweet optical system for astronomy! It also includes a collimation cap and center-marked primary mirror for easy optical alignment.
The 130ST telescope comes on an optional EQ-2M or AstroTrack electronic drive can be added for automatic tracking. An optional EQ-2M or AstroTrack electronic drive can be added for automatic tracking. The adjustable aluminum tripod is strong yet lightweight and includes an accessory tray.
Whether you're looking for a better-quality first telescope or a portable telescope to complement your big Dobsonian, you'll love the Orion SpaceProbe 130ST EQ Reflector Telescope.
