Hello, everyone, and I'm seeking advice on the ergonomics of how
to use a 9X50 straight finder with a minimum of neck strain.

My experience is that to use a straight through finder, you often have
to bend or squat and look up, which will just about maximize neck
strain. You have two strategies: either get the finder low enough so
you can see through it while sitting on a chair or stool or get the
finder high enough so you can see through it while standing straight.
Some dobs are tall enough for you to stand straight. For others you
will have to raise the base. You can put longer legs on the base
pretty easily.

Otherwise you can put in a right angle finder. One with an amici roof
prism will have a view that is correctly oriented and is easier to
use.

A Telrad will help you get in the right part of the sky regardless of
the type of magnifying finder you use.

A adjustable chair increases the comfort factor.
