at the official German Takahashi distributor, I found a reference to the tube length of the FSQ-85EDX with retracted dew shield to be 32cm (12,6 in) only. Everywhere else (even in the technical specs at the same site) I read it was 53 cm (20,8 in). I'm asking because I am seriously considering this refractor as an airline travel telescope. European airlines generally have carry-on luggage limited to 55cm length, so I feel a 53 cm refractor is a bit too long to safely package. I suspect the 32cm might be with the focuser removed. If so, how easy is it to reattach without introducing tilt? Any other tips for safe airline travel?
Thanks for your help!
