Mine was set to .5x although I had the CG-5, not the CGEM.

Just make sure your step size is smaller than the # of seconds for your exposure (so if you expose for 4 seconds, you better not go above 4000ms).

Why?

Calibration step and exposure happen sequentially. A 4 second guide pulse and 2 second exposure would just mean 6 seconds between iterations.

Unless I'm missing something. Don't think I've ever needed a cal step above 700ms or so.

Well, I just learned something new. There is a reason why I'm in the beginners/intermediate forum. :)

I use a calibration step of 3000ms but I have my tracking rate at .5x. My guidescope is a 50mm finder with 162mm focal length. So things don't nudge very far.
