Pat: Your suggestions are pretty close to how I'm going to do it. That's based off the time I spent with the owners manual and replies here. The one difficulty I experienced when doing this with my 500 lens was trying to keep the moon in view at 10x. It's amazing how fast it moves and I had a bugger of a time keeping it in view. Now I will be using a Wimberley head so I expect it to be easier to track.

Thank you, gary
