You know, that 201 is not a bad guider, once you've found (and can
easily repeat) the focus point. The 201 is VERY sensitive to that
point. If you barely miss it, you're out of luck. Also, I suspect that
your warm evenings will lead to more problems. On warm evenings here in
Southern Oregon, it sometimes gives spastic readings.

ST-4s OTOH, have a much wider range of 'good focus' points. I have no
idea why that is. Both have advantages depending on application.
