  • 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!

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.

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 EQ-2 equatorial mount and included accessories described below make this one sweet optical system for astronomy!
