8" f/4.9 (1000mm fl) Newtonian OTA that came with my Orion Atlas mount. Same as catalog #09898 OTA sold by Orion, described on their website as follows: parabolic mirror optics, aluminum rack-and-pinion focuser, eyepiece holder, quick-collimation cap, dust cap, and dovetail base for finder scope. Aperture: 203mm, focal length: 1000mm (f/4.9). 2" collimatable focuser with 2" and 1.25" eyepiece holders. Recommended for visual use or astrophotography. Includes camera adapter. Weighs 16.5 lbs.
Optics on this scope are extremely good, showing clean airy disc in focus and nice, circular diffraction rings out of focus. Condition is essentially like new. With a pair of tube rings, $225 + shipping.
