Hi Matthew
From memory it will plate solve with about 8 stars as a minimum. I am running 1 second exposures and getting it to solve easily. I was imaging last night and was using a 1 second exposure with about 10 stars showing up on the image and was successfully solving.
A quick approach to know if it is working is to do a closed loop slew (CLS) - select a target and tell it to CLS. This should trigger the mount to slew to the target and take an image, this will then attempt to solve and if it does it will trigger another slew to center the target and take an image to confirm. If it fails to solve, it will try an error message and fail. If this happens, I just increase the exposure time a bit and have another go at the process.
I just remembered that it is necessary to use the same binning when doing the CLS as what is in the image link settings. I use 2x2 for T point runs and focusing, but use 1 x 1 for imaging and CLS. It has a fit and will fail if the resolution is not correct for the CLS.
