Thanks folks.
There was a slight breeze yesterday and the tripod I was using wasn't really up to the job. This scope is well over a grand to buy new and on it's first outing, a few weeks ago with a sturdier tripod, seemed to perform better. Now that I know the 'standard' which I should expect, from your comments above, I can more easily judge when I get a better tripod and have more time to play.
Thanks again.
