Add your own accessories to the Orion ShortTube 80 and it will become a fantastic astronomy telescope that is portable enough to take anywhere. 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.

Multi-coating on all air-to-glass optical surfaces of the Orion ST80 ensures maximum light transmission for sharp, accurate image fidelity.

If you are looking for a lightweight, fast guidescope, consider the Orion ShorfTube 80 OTA. It will attach easily to your larger primary telescope tube assembly with the proper rings and dovetail, and will accept your digital SLR, small CCD camera, or a stand-alone autoguider.

For $130 each, get 2!
This scope is awesome for $130!! After I got it, I picked up a 99% dielectric diagonal, and took it up to a dark site. Dropped in my 32mm Telvue plossl, and BAM.. There was NGC 7000, North American Nebula! I think it goes to show, that an 80mm scope for $130 that can show you NGC 7000, is worth getting.. period!! Everything from a plossl to a nagler, is tack sharp edge to edge, and contrast is great! This is a must get scope!

Product Questions

Hi ,Has it got a Tripod mount.what size eyepieces will it accept.
Can I combine this OTA with the Orion 105mm Guide Scope Rings (OR-7381) and the Orion Guide Scope Ring Mounting Bar (OR-7382), and then install them on Celestron 8" EdgeHD OTA with CGE Mount Plate(CE-91030-XLT)?
Hi, I purchased this model of Orion ST80 some time ago--this Item # (OR-9948)--which does not have any mounting hardware with it--no mounting rail, mounting rings, etc.--to use as a guidescope on my larger SCT, but now I've decided to use it all by itself, mounted to my Vixen Porta-II alt-az mount. Can you tell me what mounting rail and/or rings I would need to get from you to securely mount this scope to my Porta-II mount? And would I need to drill holes in the ST80's tube to attach the rail, etc??
