This is the model 80/9D, it is 78mm objective at f/9.6. Check out the Stellarvue site for more information on this scope. Note it is like the picture of the one shown on the mount on the top of the product page, with no stickers on it.
I took this on trade recently but I have decided to sell it as I have 2 other refractors. It is optically excellent and a good value. There is one blemish on the dew shield - kind of a light scrape but it's minor. It came to me this way and I don't know more about it. There is no dent, superficial only.
I am selling the OTA, rings, 2" to 1.25" reducer and will include an Orion 1.25" diagonal a surplus shed 11.4mm which I received with it. Also it will come with a mounting plate which I have used to put it on a Telepod and also a standard camera tripod (which works reasonably well at low power).
$275 delivered in original carton in conti-US. (The OTA is $449 new, plus shipping, and does not include diagonal or eyepiece.) Paypal accepted.
