Since telescopes come in all shapes and sizes, the eyepiece height will vary, even when using the same tripod. Orion SpaceProbe 130ST Equatorial Reflector Telescope The Orion SpaceProbe 130ST reflector telescope is perfect for the more serious beginner or intermediate stargazer. But if I have more magnification the more detail I’ll see. I think a 25/12/8mm set of the Dual ED's would be much more useful. Referring to the manual is recommended. This charge varies based on the shipping method. A universal attachment system for holding the optical tube onto the tripod. for convenient transport. Astronomical also has been the sole support for Cloudy Nights since about 2005. But anyone with the slightest technical bent will have no problem getting familiar with these models. The SpaceProbe 130ST is the short tube version of the popular Orion 130EQ reflector telescope. The atmosphere above us is constantly in motion, and it will distort the image seen through the telescope. Counterweight shaft For telescopes, the optical diameter (also known as aperture) is the size of a telescope's main light-collecting lens or primary mirror, measured in millimeters or inches. Beginner Level - Suited for a wide range of uses, these telescopes are simple to operate and set up. Intermediate Level - These scopes offer higher performance and more advanced features than Level 1: Beginner models. Secondary mirror obstruction by diameter: 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. Any suggestions??? This is important to keep in mind when observing astronomical objects which require high resolution for best viewing, such as planets and double stars. Orion 130mm, f/5 reflector telescope optical tube assembly The Orion SpaceProbe 130ST reflector telescope is perfect for the more serious beginner or intermediate stargazer. Reflector mirrors are made from glass with different levels of thermal expansion. With a 130 millimeter parabolic primary mirror, the 130ST provides great views of deep-sky objects on the included EQ-2 mount and stable tripod. With a 130 millimeter parabolic primary mirror, the 130ST provides great views of deep-sky objects on the included EQ-2 mount and stable tripod. Dust cap Accessory tray bracket The focal length is an inherent specification of a mirror or lens and is one of the factors in determining resultant magnification for a telescope (along with the focal length of the eyepiece being used). The astro-photographic capability of the telescope is based on the style, stability, and accuracy of the mount and tripod. The Orion SpaceProbe 130ST reflector telescope is perfect for the more serious beginner or intermediate stargazer. I had a Space program 130ST and had a lot of fun with it. Much more important to observe deep sky objects will be access to a dark site. Binoculars with larger objective lenses are recommended for low light situations, and binoculars with at least 50mm or larger objective lenses are recommended for pleasing astronomical observations at night. Reflector telescopes use a pair of large and small mirrors to direct incoming light to the eyepiece. Refractors use a series of lenses to provide a clear image. Cassegrain telescopes, such as Maksutov-Cassegrains, "fold" incoming light using two mirrors and a front "corrector" lens. They have exceptionally fine optics and mechanics. The limiting stellar magnitude is a measure of the faintest star you can see through the telescope. The 130ST has a 24” tube compared to 33” in the 130EQ. Larger EQ mounts that utilize very precise tracking and excellent stability are capable of longer exposure deep-sky photography. When an item is not in-stock we will ship it as soon as it becomes available. Very good optical and mechanical quality. For an EQ tripod the mount is set up so the counterweight shaft is horizontal, and then the height is measured from the ground to the center of the mounting plate. Astronomics is a family owned Astronomy store that successfully transitioned into the internet age, many didn't. It came with a 25mm and 10mm. Telescopes with larger optical diameters collect more light, which leads to an increase in brightness and image resolution compared to smaller instruments. Many of these eyepieces are the same eyepieces but go by different names. Motor drives are usually equipped with a hand control that allows the telescope's tracking speed to be slightly increased or decreased, which is particularly critical when taking long-exposure astro-images.
