These scopes have a cult following world wide and from what I have read they are every bit as good as the AP or Tak 6 inch APO's , just a little less light grasp that's why they hardly ever come up on CN;s or Astro mart their owners seem to hang on to them and are snapped up fast when advertised.
I to are interested in the TEC's performance compared to the 102mm Takahashi , my thoughts are the 102 being smaller was less effected by local seeing ? .
