For quite some time I wanted to use my 10” Newtonian for prime focus deep sky AP.
The only obstacle was low-profile focuser – to reach the focus it needded to be shorter than 35mm and I could not find anything suitable on the market, so I decided to build my own.
Recently I found time to finalise the drawings, and a friend of mine helped me to make it in his work shop. I decided to use the Crayford design because it is relatively simple to build (at least for me).
The results of that effort are attached below.. the only things that are still pending are M42->EOS adapter and a holder for the stepper motor.

The conical interface is my internal standard - long time ago, when I build my Newtonian, I sort of planned for the interchangeable back end. It was inspired by 130mm Zeiss refractor and it's mechanical design at the Astronomical Observatory I was spending my evenings on as a school boy.
The existing focuser can be replaced with this photographical one in couple of seconds.
