Quote:After many comparisons (even with the Zeiss APQ-100/640) I wouldn't give the following one away for any of the above 4-inchers:
(just move cursor on pictures to enlarge)
Since this multi-coated and (other than the APQ) air-spaced 100/640 fluorite-triplet is not available new any more, I personally would go for today's TSA-102/816 that has very similar characteristics of performance to the FCT-100.
Quote:Any scope made by Astrophysics from the late 1990's onward would be my picks.
Quote:Quote:Any scope made by Astrophysics from the late 1990's onward would be my picks. The difference between Televue refractors and Astrophysics refractors is the lenses. Televue refractor lenses are made of very exotic glass, but Astrophysics lenses are made from unobtanium.

Quote:This thread has not only very high quality scopes in it but has about as much "brand loyalty" built into it too. I'd definitely agree with you Rutilus. If he believes that his Carton 100mm F/13 ranks right up there with Taks I think he has a valid point. Therefore being an Istar lens user I'd definitely place Istar's triplets and fluorite ED's right at the top of the mix. I definitely believe the Istars are the "sleepers" currently available! Mike
Quote:Refractors new available under $6K:-Takahashi TSA-120.-Takahashi TSA-102.-TEC-140.-Tele Vue NP-101.-Tele Vue 85.
Quote:I like Barry's standards for attempting to segment the refractor field. Then I completely disagree with Astro Baby as emotion, and lack of exposure to other product governs his decision. I realize it is hard to be pragmatic if your experience is limited. But, if a,top 10 can be created by segment (as Barry suggests) then that would be a fairly largely inclusive field. Not every scope made in Siberia or Mongolia would likely make it, but that is not unexpected.
