Debbie, if he was using it with a telescope that would fit on a Losmandy mount, it was probably too-small, or marginal. That parallels my experience. It's a great product, but not really suitable for small apertures. Even 10" is pushing the small side for the Easy-Guider. Many (most, it seems) objects just don't have a bright enough guide star at the right radial distance from the center of the field, this can be frustrating and you can't always compose the shot just the way you want it as a result. No competent reflecting telescope maker would design for 100% illumination 1" off-axis unless it was a dedicated imaging system like a Schmidt camera or similar, and not many amateurs can afford a 12" refractor (except for Al George, who has a 15"!) One a large scope, it would work much better. That said, the principle of the off-axis guider is excellent: Guide with the same optical train as the one you're imaging with, and you eliminate differential flexure as a possible source of trouble. The bigger the image scale, the greater this problem can be. I use a separate guidescope on my small set-up. Debbie wrote:

I guy e-mailed me from the Losmandy yahoo group the other day and he had trouble using it and sent it back. I'm not considering that option anymore. I'm now looking into a guidescope on a dual scope platform right now. Thanks for the feedback.
