The ST80-A (for "Astronomy") is an upgraded version of the ever-popular Orion ShortTube 80 telescope. Now improved with fully multi-coated optics and a soft carrying case, the "little scope that could" is better than ever! The Orion Short Tube 80 is a fantastic astronomy telescope that is portable enough to take anywhere, and you'll love its bright, wide-field views. The 80mm objective lens and short 400mm (f/5.0) focal length are perfect for taking in wide swaths of the heavens, making it ideal for larger deep-sky objects. You'll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system. Enjoy experiencing the phases of the Moon and tracking the motions of the planets with crisp views of Saturn's rings and Jupiter's moons.

This scope has been a favorite with amatuers for a very long time. I was very impressed with all the machine work and the tightness of the focusser. With the improvements to the coatings and the two Wide Field Eyepieces, it is an unheard of bargain. It also has a cradle mount so the tube can be rotated to any position. I live in the center of the City of Escondido and the views were very impressive!! At low power, abberations are not noticeable. I also use it for Birdwatching!!!

- Questions & Answers
Product QuestionsWill this mount up to all my 35MM photography tripods or do I need to buy anything else? If I need anything else, can you tell me what it is and is it in stock? Thanks!
MikeHow well will this work for astrophotography? I'm looking to add a portable telescope for DSO imaging. Currently have a 9.25 Evo from Celestron but want a wider field. Also, recommendations for a EQ mount for this scope would be great. Not sure if I plan to move up to an EQ mount for my 9.25 yet.Question by: Kevin on Dec 17, 2016 7:54:00 AMUnfortunately, while this scope works well as a guide scope and for low power visual observation, it is not well corrected for DSO astrophotography. It is not apochromatic, so there is a lot of chromatic aberration on top of the coma and field curvature, and with a 1.25" focuser there is no way to fit a typical 2" format field flattener on the back. The focuser will support a light CMOS or CCD guide camera, but it is not designed to handle the weight of a DSLR or larger CCD camera with filter wheel.
Any manufacturer's EQ mount designed to carry at least 25 lbs will typically do at least a decent job for astrophotography with an 80mm scope, but I would recommend considering a scope designed with astrophotography in mind instead.Answer by: Chris Hendren on Dec 19, 2016 8:33:00 AM
