They are very good images Paul, especially via hand focusing. Well done. I watched an on-line presentation on ccd imaging techniques at
http://www.ewellobservatory.com/bestpractices/index.cfm where the author demonstrates, very effectively, image degradation due to lack of perfect collimation resulting from turning a single Bob's knob just 5 deg on a C9.25.
Well worth a look if you have broadband.
