I was getting oblong stars at any exposure length, and I thought it was the collimation. I just got an ASI290MM-mini camera, plugged it into the Stellarvue 80mm finder and started guiding. With the guider I got perfectly round stars at any exposure up to 5 minutes. I'm in a Bortle 8-9, so anything longer than that is saturated. I was amazed at how simple it was. I did encounter a problem calibrating, but I have an LX600, and it has a built-in autoguider which was fighting the internal guider. Duh. When I turned Starlock off, the guider took off and worked perfectly. I just wanted to say that it has made the biggest differrence of anything I've tried, and I think it completes my system.

Thanks to all who have worked on the autoguider!
