Hi All,
If I have done this correctly,you should see a little unit I made up for using binoculars,on a swivel chair.
it is simply a frame that is held in place by your thighs,it has a padded bar across the top to rest your arms on.
to look lower you spread your arms wider,and to look higher,simply bring your elbows closer together.
While it is no substitute for a good tripod,it does remove a lot of the movement.
I did get my wife to take some pics of me using the helper,but unfortunately they didn't turn out.(dont ask)
Regards.John
