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,

Howard
