description Orion SpaceProbe 130ST Overview

The Orion SpaceProbe 130ST is a Newtonian reflector telescope featuring a 130mm (5.1-inch) primary mirror and a shorter optical tube than standard models, enhancing portability while maintaining light-gathering capability. The "ST" designation stands for "short tube," providing a wider field of view suitable for observing larger celestial objects like star clusters and nebulae. As a Newtonian reflector, it uses mirrors rather than lenses to gather and focus light, offering good value per inch of aperture, and comes with an equatorial mount that aids in tracking objects as they move across the night sky, making it appropriate for beginning astronomers.

help Orion SpaceProbe 130ST FAQ

What are the optical specifications of the Orion SpaceProbe 130ST?

It is a Newtonian reflector with a 130 mm primary mirror, 650 mm focal length, and f/5 focal ratio. The short-tube design makes the optical tube more compact than a longer 130 mm reflector with the same aperture.

What magnification do the included eyepieces provide?

The standard kit includes 25 mm and 10 mm Explorer II eyepieces. With the 650 mm focal length, they provide approximately 26x and 65x magnification respectively.

Is the Orion SpaceProbe 130ST easy to carry?

The optical tube is relatively compact, but the equatorial mount adds substantial weight. The manual lists about 6.9 pounds for the tube, 21.5 pounds for the mount, and 28.4 pounds for the complete setup.

What can I see with the SpaceProbe 130ST, and does it track automatically?

Its 130 mm aperture is suitable for the Moon, bright planets, and many brighter deep-sky objects when conditions are good. The German equatorial mount is manual in the standard setup, while motor drives were offered as an optional accessory.
