Maybe eliminating shake isn't the right description, my approach is more everything shaking together = no shake .... Einstein was right "it all depends on your frame of reference". A small piece of thin plywood scrap, a tongue depresser, a 1/4"-20 TPI knob and a scrap piece of pine. The seveal holes in the plywood base are to accomodate different cameras I've used.

A pedestal holds the flys. It is a miniature test lead clip found in an electrical supply store, a dowel spacer and a button magnet. It clamps to the washer on the tongue depressor in use and stores on another washer so it doesn't get lost.

Here's the ready to shoot picture taken more or less from the front.	And another taken from the side.

I'm all (un)shook up.
