>The whole image appears a bit soft to me.

Yes to me as well; the image is enlarged in View to 1:1

20 feet, maybe 25.

Yes, or a point near to it.

>3) What was the focus target?

The bolt

>
>4) I assume you were using autofocus, correct?

Yes

>
>5) Was the wind blowing? If yes, how strong?

No wind, the camera was set on carpet (hmmm) in my living room and the shot was made through the patio door. (the door was open)

base plate

The tripod is more than adequate as is the support package for the lens.

Yes

balanced so that I could have the tilt loose and it did not move; it was centered.

Tripod is adequate, load balanced, no wind.

I do not know.

random, as far as I know.

I paid a lot of money for this 600mm lens, it better not be a lens problem. If it is, and if it needs repair, then I need to get on this now to have it ready for Yellowstone.

I followed the advice of Moose Peterson and had the gimbal head loose, I watched his videos and set my system just like he did. hmmm, maybe that is not a good idea. I'll take a few more pics with the head locked. That might be the issue. If so, then how does he do it?

Bear in mind, this is the best of the group; the others are blurry
