The design of the TSA is pure triplet, whereas the TOA is well-spaced triplet. The new fluorite FOA shares the same design principle, and is one of the highest Strehl production scopes ever made (it's for all intents and purposes a poly-Strehl of 0.995)

Thanks Lewis. I wondered why I could only find the TSA120 listed.
What's with the tiny focuser and no dual speed at US$4430?
First thing would be to throw out the focuser and put a Feathertouch on it.
FOA is only the 60mm right? Sounds good but very small aperture.
If they could make a 110mm FOA it would be attractive.
Greg.
