Hi, I've received photos from you through email. The photos show that it is not the TMB carbon fiber tube telescope which is displayed on the Astronomics internet link above (selling for US$1395 new).

Hence i will not be buying it. Thanks.

Perhaps you could put up some photos here.

I think the OP mentioned above that it is the lens from a TMB 80CF, in a DIY Alu tube and probably a Jinghua or Synta 10:1 Crayford.

Edit: it's a triplet so not equivalent to the usual 80mm ED tubes out there.

I believe this is a TMB-designed but fabricated in China lens.. so kind of equivalent mechanically to an AT80ED ($750 USD -- or similar) but with the triplet lens. Not too bad a price I suppose.. although would be concerned if the focuser is orthogonal to the DIY tube.

the lens made in taiwan.i cant say anthing,if who want ,i will take some pho by tmb80CF,let you see the Phase field and star point.thanks

AT80ED is a 80/F7,this one is F6.3,Totally different.

Upz..
