I have downloaded the trial version and have been taking it for a spin. I must say ACP is an elegant observatory control solution. I have been extremely impressed.
And, to a large extent, I have been successful. Solutions to my problems I have typically found in the documentation.

I began using the filter offsets and this has worked very well. However, after the first autofocus, ACP tells the focuser to add 3 for the Ha filter and then Robo Focus states valid range is 0 to 1 OK? The program will stop running until I click OK. After that all subsequent filter offset changes are made without incident. I have seen two posts related to this on the FocusMax yahoo group but no answers to the problem were noted.

Any light shed on this would be helpful.

Best Regards,
