Hi Peter,
Thank you for your comments. I have been looking at this for a while. I run everything automated, currently using a guide scope. Stars are always present, even after a meridian flip. But, I will be increasing my focal length and have been looking for a reliable way to locate guide stars before and after a meridian flip. That's why I was asking all the questions. I have a gut feeling that I would have to manually locate a guide star as my guide camera has to small a chip. Are you using the ONAG in an automated fashion. Like you, I am away from the scope. Makes some things difficult at times.
