 The Clear Sky Chart for my area indicates a long clear night coming up. So after going to the local fireworks display, I hope to get the scope out and aligned and sort out Liveview focusing! I've posted a question on Canon DSLR Digital Astro Yahoo tech groups and gotten several helpful suggestions. I also reviewed Jerry Lodriguss's website on using Liveview for focusing and I think based on all this I was very close the other night. 
 
I believe my biggest problem was not getting the prefocus close enough to correct before attempting to use Liveview with the wide angle lens. Tonite I will prefocus on the crescent moon in AF mode at ISO 1600, then keep the focus unchanged, switch to MF and Bulb and then put the camera on Vega to try focusing on the brightest star visible at that time of night. 
 
The article on Jerry's website can be found at:
 
 
I suspect others have had the same problem as beginners. I will update the journal tomorrow to report on my success, hopefully with photos!

Thanks for the insight on Nebulosity Barry. It sounds like a program that will take a lot of the pain out of the focusing process for sure. I am evaluating it and Images Plus but currently have spent my AP budget for a few months. This program is currently on my "wish list" along with some good eyepieces for visual observing, a 12 volt deep cycle battery for taking my telescope more than about 15 feet from my car when I setup and not having all the power cords to trip over a few other things! This hobby is like fishing, there is no end to the "wants" and needs. Appreciate you taking time to post, good to see that these journals are looked at.

I use a capture program called Nebulosity. It makes focusing quite easy. You first set the camera to 5 second exposures and click the "Frame and Focus" tab. The camera clicks off 5 second shots while you get focus close. Then you click the "Fine Focus" tab, and click on a medium bright star. Then you watch the numbers as you do minor focus adjustments. The top number will be around 65,000 when seeing is decent....a dual speed focuser with a fine focus knob, helps.
