 I also initially used the smallest calibration I could make the unit say
 hello with. C1=3 and C2=4. But my
 corrections have been way too high. Last night I tried several higher
 calabration times.  I got the best 
 guiding with C1=6 and C2=8. Maxx, in your reply to my original post on
 SBIGuser I noticed you use Ca=9.   
 Yes, the smaller corrections seem fairly consistent except for some very
 weird "anomalies".
 Last night I would be tracking along with average corrections from 2 to 5,
 then all the sudden I would hit a bunch of 
 E's. The relays stop clicking sometimes; I keep wondering if the unit
might
 have a problem. I also thought
 that ex. times of 2 and 3 seconds gave smaller corrections than ex. times
 of .5 sec. I was told once that 
 the lx200 drive can't respond fast enough for quick intervals of
 correction.
