The 10mm Explorer II eyepiece offers you a closer look into the deeper night sky. This allows you to apply more magnification into your telescope. It has a 90x power view when used in the SpaceProbe 130 reflector telescope, which is why it provides closer look. 

The telescope also comes with a 6×30 finder scope that could ease your telescope aiming, collimation cap, dust cap, accessory tray, and Starry Night software.

The 6×30 achromatic finder scope helps you to aim the telescope accurately so that you can also view the celestial objects like the Moon, bright planets, star clusters, and distant galaxies clearly. 

The EQ-2 mount and tripod that gives slow-motion control and stable support will allow you to have a fine manual motion of the telescope and you will be able to track and keep the objects that you want to see in focus.

The Starry Night Special Edition software can be used as a way to learn more about the night sky at anytime you want even though it is cloudy. The software will give you realistic sky simulations that can be used to see what stars, constellations, planets, or other celestial objects are visible on any day or at any time.

The software also comes up with many features that require the use of PC with Windows 10 or Macintosh with OS X 10.10 or higher, which can be used to control the telescope and help you setting up your fascinating night sky observation.

Orion SpaceProbe 130ST (09007) Equatorial Reflector Telescope

This telescope weighs only 27 pounds when assembled, really close to the weight of the 130EQ. SpaceProbe 130ST Equatorial Reflector Telescope is the upgrade version of the 130EQ which is designed for a more serious beginner or intermediate night sky explorers.

The new feature offered by this telescope can be identified from the name itself. The term ST on the name stands for Short Tube, which refers to the telescope’s optical tube that measures 24″ compared to the tube in the previous version that measures 30″ long. 

This makes the telescope becomes shorter and more compact, which makes it further easier to be carried around or provides portability. Besides being short and compact, the other features offered by this telescope are also some standing points which make it different from the previous version.

This Orion SpaceProbe 130ST provides a wider range of view and brighter images for the telescope’s eyepiece focal length since it is packed with 130mm primary optics and 650mm (f/5) focal length.

The 130mm aperture is a diffraction-limited parabolic mirror that is commonly used on much larger reflector telescopes. This choice of parabolic mirror is a perfect combo for the short focal length design since they can work together on focusing incoming light and then providing sharp, clear, and detailed images. 

The secondary mirror that is held with thin 0.5mm metal vanes helps in reducing diffraction spikes and light loss. When it is combined with included EQ-2 equatorial mount and other included accessories, this telescope will be just great!

The aperture of this reflector telescope works to collect the light and provides great views of the celestial objects while the f/5 focal ratio provides wide range of view of the starry night sky. 

The telescope is also equipped with sturdy EQ-2 equatorial telescope mount and adjustable tripod for comfortable observation, a 6×30 finder scope that could ease your telescope aiming for more focus, accessory tray to store your telescope accessories, collimation cap, 1.25″ rack and pinion focuser, and Starry Night software that could help you learn more about the night sky objects.

There are two eyepieces included in this 130ST telescope, which are two 1.25″ Sirius Plossl eyepieces (25mm and 10mm). The 25mm Sirius Plossl eyepiece is a great start to begin your night sky exploration since it gives modest magnification of 26x power view. It also offers a wide 52° apparent field of view. This makes the eyepiece capable of providing clear and crisp image of celestial objects like the cratered surface of the moon.

For a closer look to the night sky objects, you can insert the 10mm Sirius Plossl eyepiece into the 130ST telescope. It provides a powerful 65x power view with a 52° apparent field of view that give you closer image of the celestial objects.
