Re: [APML] Guiding a TV-85 on a GM-8 with an ST-4

Alan,
        Getting mostly 0's & 1's you are doing great. From my limited
experience, I would tend to think that the seeing changed on you and caused
the bad numbers, and even caused it to lose the guide star (the beep you
heard). I can't be much help on how to rectify this, since I am still
working through the optimal settings myself. I keep Jim Janusz's
instructions at close bay when I am using the ST-4..he's pretty detailed.
