I am considering getting a larger refractor around the 130 to 140mm size. I was hoping my name would come up on the AstroPhysics 130GTX list and it might at some point but I can't plan on an uncertainty.
I have had a TEC180FL in the past and it was a very nice scope overall. Perhaps more optimised to visual than imaging. Dr Rhor's test though surprised me showing it did not perform that well in the red channel. Images I took with it were good but often less than what I expected if only by a small amount.
I have a CFF105mm F6 and it is a superb scope. I am impressed by the workmanship both optically and mechanically. I've been told the main optician used to work on the Zeiss high end scopes. Don't know if that is true but it may well be. The strehl test report for the CFF105mm F6 is 99.4%. I presume that is in green and it won't be the same polychromatically (all colours).
I had an AP140 F7.5 with an APquad TCC and it was a nice scope and images with it had that little extra I wasn't getting with the TEC180.
I also had a TEC110 FL and it performed better than I expected with wonderful rich colour compared to the FSQ106EDX3 I had previously been using.
So the top 3 scope makers at present seem to be TEC, CFF and AP. Unless you can think of a 4th. APM scopes seem fine but strehls are lower than these others. Also the focusers etc seem a bit chunky. Featherouch focusers are what I want these days and not as an after market conversion.
As I can't simply order an AP130GTX that leaves trying to get one 2nd hand at inflated prices. Perhaps that still is a contender.
So what say you about TEC140FL F7 versus CFF140 6.5 or CFF132 6.7?
TEC has an advantage in that it can use the APQuad TCC which makes it much faster. The TCC may work on the CFF but that would have to be confirmed. All 3 are oiled triplets. The TEC has a centre lens of Fluorite the CFF either FPL 53 or FPL55.
I did read one review here between the 140ED and the 140Fl and surprisingly it wasn't all in the 140FL's favour.
Both scopes I think are fairly light and easy to use.
