Yes to me as well; the image is enlarged in View to 1:1 > >A few questions: > >1) What was the camera to subject distance?
20 feet, maybe 25.

Yes, or a point near to it.

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)

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

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

Tripod is adequate, load balanced, no wind.

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
