Thanks Allan - that is helpful
I had another play with it last night. I can't bring the SSAG to focus with my set up - not because there is not enough travel out, its insufficient travel in. In other words, I rack in the focus as much as possible and still can't quite get the stars tight enough.
I suspect this is my issue - as the stars are smeared, the SNR is not high enough for Maxim to pick up when calibrating. So Maxim moves the mount and the stars appear to move but I don't have this registered by Maxim.
I souped up the exposure time to 10 seconds and was able to calibrate it once last night - but I couldn't repeat the trick.
I find this odd. Does the acrylic disk change the path of the light? I assume not. Then how do others with the RC8/QSI combo manage to get to focus?
