I bought this nearly a year ago from a Canadian vendor and I've forgotten the specific focal length. It is 80mm for sure. By my measure, it's about an f10 or f11, making it about 800mm to 900mm, a good FL for a guidescope.
Like most of these little refractors, you'll need a diagonal to reach focus. The metal rack&pinon focus mechanism is pretty smooth (smoother than my SCT) and it has a focus lock!
As you can see from the picture, the coatings aren't Televue quality, but then at $80, you can't even buy a Televue eyepiece. It really performs better than the picture of the front objective might lead you to believe. I saw no false color viewing a full moon or at 2 or 3rd mag stars.
Like new, though there appears to be a mote of dust caught between the object elements. I didn't notice the dust mote in either the eyepiece or the guide camera frame, though.
Comes with small finder and front lens cap, removable dewshield and clamshell type ring (it's pictured, if you don't know what I mean by clamshell.)
$80 + actual shipping charges CONUS. Paypal prefered. USPS money orders accepted, too. No personal checks, please.
I also have a converted Quickcam Grayscale camera for sale. If you're interested in the camera, too. We could work out a package deal.
