The popular Orion "little scope that could" is now even better. The Orion Short Tube 80 is a wide-field refractor that novices appreciate for its ease of use, and that owners of big telescopes value as a take-anywhere second scope. The Orion ShortTube 80 has been improved with fully multi-coated optics, and it even comes with its own padded carrying case.
Orion Short Tube 80mm Terrestrial Package
The Short Tube's 80mm achromatic objective lens, short 400mm focal length (f/5.0), correct-image diagonal (1.25") and 6x26 correct-image finder scope make the ST80-T perfect for casual stargazing or terrestrial viewing. The short focal length means you'll see a beautifully wide field of view. And like all refractors, the unobstructed light path of the Orion ST 80 means sharper images with better definition and contrast.
Despite its diminutive size (it's only 15-1/2" long) this telescope really delivers, and it's so portable you will be able to take it virtually anywhere. The Orion ShortTube 80T comes equipped with a 1.25" cast-aluminum rack-and-pinion focuser and two interchangeable Sirius Plossl eyepieces...a 25mm (16x) and 10mm (40x). It attaches easily to a wide variety of equatorial mounts or photo tripods, and has a one year limited warranty.

- Orion 80mm Short Tube
Superb scope!! It gives you correct orientation of your view left to right. It is a great scope for Astronomy too, as the image orientation doesn't really matter in Astronomy. The 45 degree eyepiece is good for short people in Astronomy. All around: It is one of the very best starter scopes you can buy for land or sky!!

- Questions & Answers
Product Questions1. Do you know what the eye relief is, I wear glasses? 2. Does the viewing lens rotate for shooting, or do you know if this comes with a strait viewing lens?Question by: Danny McReynolds on Apr 9, 2015 12:43:00 PMThe Orion ST80 Terrestrial Package comes with 25mm and 10mm eyepieces. The eye relief of the 25mm is approximately 15mm and the 10mm eyepiece is approximately 6mm. The eyepiece can be rotated for easier viewing. You can use the telescope with the eyepieces straight through with an extension tube seen here:http://www.optcorp.com/orion-1-25inch-eyepiece-extension-tube-5123.htmlAnswer by: Todd R (Admin) on Apr 9, 2015 4:01:00 PMQuestion by: Terence on Mar 8, 2014 9:35:01 AMThe manufacturer does not list this spec, but it depends on how many extension tubes you use.
The farther out you rack the focuser, the closer the resulting focus will be. If you add an extension like this http://www.optcorp.com/orion-1-25inch-eyepiece-extension-tube-5123.html, you can focus even closer, and these can be stacked. The practical limit is probably around 10 feet distance from the scope before the amount of extension on the focuser becomes ridiculous and image quality suffers. Telescopes are optimized for infinity viewing, so aberrations can be magnified by focusing at a very different distance.Answer by: Chris (Admin) on Mar 11, 2014 8:53:39 AM
