Credit where credit's due!! Thank you Mr Watkis.
Credit where credit's due!! I Agree.
I have no books on Spectroscopy directly, amature or professional, so I have been relying on the info presented in this forum.
I do have some books that contain basic info on stellar spectroscopy and a general knowledge sufficient to teach secondary students.
The work of C.J.Watkis, albeit gained by second hand, has been inspirational.

Having said that, here is my beefed-up mirror rotator screw. It works much better that the 1/4" thread before.
Now working on the 2" nosepiece.
