I agree. I had no end of problems trying to find one with the standard 840 ToUcam. Depending on where I was pointing and the density of stars I found even a camera that could go for a full second at times had trouble getting a decent guide star. Needless to say I cut my losses and took the easy way out with a guidescope. Now though I'm just waiting for the clouds to clear to use the ST 7 with it's own built in guidechip. No more flexure, no more adjusting guiderings. Sweet as.
