James: Impressive. Is the snake behind glass or is she not dangerous??? With the 500D the subject distance is quite small...
Thank you, Frank.
The snake is not dangerous and is not behind glass. I used a setup similar to what is shown in the attached picture (not sure why it is sideways...). Basically, I have a hiking staff onto which I have mounted the red threaded "ball" (made by Manfrotto), attach a pair of little legs to make a sort of bipod arrangement, and use a Really Right Stuff BH-25 ballhead to hold the D800 (I had the ballhead on the top rather than out in front as shown.). I put the camera in Live View and use an MC-30 cable remote to release the shutter. (I also pop into the menu to allow the shutter button to activate focus...usually I use back-button autofocus, but that's no good here.) By maneuvering the far end of the hiking staff around I can position the camera where I want it and watch the screen to get the focus point where I want it. You can also zoom the live view image in a bit. To avoid focusing on the tip of the snake's nose I had to sort of catch the eye with the edge of the focus area; a bit tricky, but I pulled it off.
Once I get a D850, the focus shift mode would be a nice help; not so much to get images to stack, but to just focus on the tip of the nose and sweep the focus through...call it focus bracketing.
Of course a wireless remote would be nice...perhaps even the much-maligned SnapBridge could get it done.
I also took pictures with the AF-S 20mm f/1.8G (which focuses nice and close) by the same basic method. I will be ordering the new 8-15 fish which would also be a nice option.
Since this all happened on my front porch, it was easy to run inside and toss all this together; my dream is to use the same approach (perhaps with the extension cord to the MC-30!) on a nice rattlesnake, like the one in this post:

(The same staff + bipod arrangement works well as a tripod against boulders, trees, or the ground...handy for a hike.)
