Bart , its a R&P , a very nicely machined rack and pinion , great 10/1 reduction race , quality drive bearings , but the problem is in its overely complex adjusting system , a real head %$#k as you need to push/pull the opposing 1mm and 1.5mm allen head screws to get any feel , over and over and over an.... oh no !!! you over tightened the left rear ,,,,
back to the beginning ,,,
Again
.over .... I cant count the times I dropped one of these tiny baby allen keys onto the dark workshop floor
.
Once set now , it seems to be good , touch wood but I have used it lots with big Nagler and Celestron eyepieces and it seems to be holding its own .
Lee ,
I love a problem , its what I do ,,,,
,,, bring it on
.
But thats only part of this scope , how are the optics ? that was the origonal Q and sorry for hi-jacking the thread Bart , but from what I have seen in the WWW these are as good as the best APO's out there no matter what price .
They are as I said before a 'FlagShip' telescope for Synta .
Once sorted well up to my visual self with my 127mm iStar
