Thanks Colin. I have a couple of days while this next snow storm passes, so I will make some adjustments. I do have one other problem that I'm not sure how to fix. I noticed on Bernard Miller's log file that there are occasions on getting the guider set that he has a few lines that say"guide error n/a or too high." Mine does that and sometimes it goes through 50 tries without getting it set right. The guide star is dead center in the guide picture, so I am wondering about adjustments. Where and what kind of adjustments do I make? LaVor
