Step 2 - how to solve ...

Description

The idea was born to modify "Astroschelle" for the lens - this is the next step - tripod-mount has been removed and the dimensions of the lens have been measured. The mod-process for the design file is in progress ...

Addendum 1: I checked how the P67-lenses are adaptet to other DSLR/DSLM-Systems. Nearly all of the adapters have a similar shape, so that the mount I have in mind as a mod of the Astroschelle will work with all under the condition, that the area of the lens->adapter connection looks like shown in the picture.
Adapters for the most common systems have nearly the same length as the EOS-adapter shows, adapters for mirrorless systems are much longer, so that camera-attachments like battery-grips are not estimated to be problematic.
My worst case is a EOS1, followed by a 400D with battery-grip and a 20D with battery-grip. My mod is planned to fit with these geometries and I hope it will fit most similar cameras of the other systems to.

Addendum 2: The release-button of the bayonet's adapter will be under the rear element of the mount, so that it will not be possible to separate the lens from the adapter if enclosed in the mount. In my mind this is no real restriction, it seems to be more an advantage because it avoids dropping the lens by accident if handling the setup outside in the dark. Separating the camera from the lens-adapter-combination will be possible, the release-button of the camera is NOT covered.

Now with the correct mechanical dimensions, sorry, but in german.
