I wrote this review to express my "consumer" impressions and opinions. Clearly, the TMB triplets show state-of-the-art optical design and display a level of workmanship that challenges or exceeds the competition. Even though I used the TMB alongside several other refractors and reflectors, I will leave the task of exhaustive direct comparison to others. I saw pleasing optical performance in the TMB that I have not seen in the competitor products, which led me to believe that I had made the right choice.
All things considered, I would say that the AP scopes have met their match, and I would bet that half of the upcoming direct comparison reviews will favor the TMB. The Taks (102's, etc) have been easily surpassed in color correction (in all fairness, the FSQ-106 is an astrograph, not a fast APO), and the TV-101 continues to be surpassed on all counts by the TMB. Having said that, I believe that the owners of TeleVue 101's will find the view a little different. Once you are accustomed to the edge-to-edge flat field of the 101's flat-field Petzval design, the curved field of a fast triplet refractor may take some getting used to. However, the TMB's gain in contrast, sharpness, and planetary performance is quite noticeable to me, as compared to the TV-101. It all boils down to your preferences and priorities. Personally, I traded the flat field of the TV for the portability and optical rigor of the TMB. |
