I'm starting to look at 130-140mm Apo refractors, primarily as a visual instrument to compliment 8-10" reflectors, but with a capability as an imaging scope when fitted with a focal reducer.
Teleskop-Service seems to have a few options in this space that represent good value with the German 19% tax deducted. Does anyone have one of these?
Of their 130mm offerings, there seems to be a big price jump between the cheapest one with a 2.5" focuser, and the f/6.62 model with a 3" focuser, which is almost twice the price:
https://www.teleskop...PA-focuser.html - 1595 Euro
https://www.teleskop...r---FPL-53.html - 2015 Euro
https://www.teleskop...on-Focuser.html - 2940 Euro
They are all triplets with at least one FPL-53 element.
Apart from the focusers and minor focal length difference, what are the differentiators?
What other scopes in this space are worth looking at? (bearing in mind that I'm in Australia and significant shipping and import duty charges will apply).
