Orion SpaceProbe 130ST Equatorial Reflector Telescope
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.
- This 5.1" aperture reflector telescope gathers an ample amount of light for great views of the planets and Moon, as well as brighter galaxies, nebulas, and star clusters
- Short 24" long optical tube design for easy portability and fast f/5 focal ratio for pleasing wide-field performance makes the SpaceProbe 130ST EQ a very versatile telescope the whole family can enjoy
- Sturdy EQ-2 equatorial telescope mount and adjustable tripod allows manual slow-motion tracking of celestial objects as they appear to migrate across the night sky
- Complete assembled telescope weighs just 27 lbs. for convenient transport
- Includes two 1.25" Sirius Plossl eyepieces (25mm and 10mm), 6x30 finder scope, 1.25" rack and pinion focuser, tripod accessory tray, collimation cap, Starry Night astronomy software, and more!
Just what's so nifty about the Orion SpaceProbe 130ST Equatorial Reflector 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 130ST reflector telescope’s 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.
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. 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. An optional EQ-2M electronic drive can be added for automatic tracking (EQ-2M drive sold separately). 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.
The relatively compact SpaceProbe 130ST EQ weighs just 27 lbs. once assembled. It’s an easy telescope to take out to your favorite stargazing spot, whether just outside the back door or in a more distant location away from streetlights and light pollution.
Whether you're looking for a better-quality first telescope or a nicely portable telescope to complement your big Dobsonian, you'll love the Orion SpaceProbe 130ST EQ Reflector Telescope.
