First time post here but some might recognise me from the other side. I have an AP Barcon and a Tak 1.6x extender. My principal use is in increasing the f-ratio so that my ADC works properly. Since I use binoviewers almost exclusively, the optical train needs to be fairly robust to handle the ~2kg load. The T2 thread on the Barcon allows versatility but I concur, it would be better if it had a M48x0.75 thread for filters. Other applications include boosting the focal length so that I can comfortably use 10mm ortho's on the moon and achieve a smallish exit pupil. I've also used my Tak extender before my Herschel wedge / binoviewer combination when making white light solar observations. It tolerates the light beam from my refractors without obvious difficulty. This is probably because I use it a long way (~220mm) inside focus.
