Looks like the one up for sale on Ebay at the moment, it used to be branded as Optex, same also sold under other brand names. They have also come up now and then on Graysonline auction sites. The one on ebay seems to have no Collimation screws on the secondary either, perhaps its covered by a cap.
Focuser is 1.25" only. I like the 8" newt's I think in hindsight I would have been better off with a 8" f/5 dob, instead of my 10" especially now that I am looking for a GEM mount for it.
