Re: What is the diameter and thread on the Pasil.4 polar scope?

I believe the AP side is English and the polar scope itself is metric and the AP bushing adapter is metric on the polar scope side and English on the mount side.
So all you will need to do is English threads to make a threaded plug for the mount. For a plug I would use Delrin plastic (easy to machine). For a plug, the threads don't need to be precise or tight. They can fit a bit loosely and still work just fine.
