I removed the back plate and put it back a couple of times, after the epoxy had set, and the repeatability is very good. The line of sight always hits the centre of the secondary hub within 0.001" .
I was watching the video about the various applications of the micro alignment telescope and read the brochure on the Taylor Hobson website. What did you exactly use it for and what was the procedure? Squaring the back plate? Centering the secondary?
