Since I am having some problems to get a correct alignment of the my CCD sensor in my WO 98 DDG, I am thinking about building an adapter to avoid inserting a nosepiece into the focuser, but directly screwing the M48 focal reducer into the part.
For that I will need the technical specifications of the thread remarked in
I have seen it is about 3.5", but I need the complete set of specifications.
Alternatively, Does anybody know if such a part exists? I mean, the same part in the picture but the camera side being a M48 (or any other "usual") thread, avoiding the 2" female?
