Re: [APML] ST-4 and AP1200GTO Use???

Hi Kent:
I can't add much to what Bobby said about the ST-4 settings, but for
calibrating the guider to the mount I'm using the default C1 = C2 = 5 and if
the keypad on the 1200 is set at more than 1x it often runs too far. So I do
the calibrate at 1x and then drop the keypad speed down to 0.5x for
tracking. Roland Christen recently recommended this and I think it does work
better than guiding at 1x, especially when the seeing is poor. To my
surprise, I haven't found too much tracking difference between SA=2 and
SA=9. I expected the 9 setting to be much better for poor seeing.
