Frank,
In this book is under: Using the instrument, the general known info about "swinging the arc"
At the same time rotate the instrument about the AXIS OF THE TELESCOPE advised'.
You learn in your workshops that this "General used advise" is usable to heights ~45°>
above that use the better method: Rotate round the indexmirror-star axis
Why can I not find your better method, rotate round the indexmirror-star axis to keep
the star in sight, in a book?
Regards,
HermanD
