Hi Bob, could you look at something for me. I'm trying to set up a 10-Micron mount. As you will see from the log, everything looks great (focusmax also works well) until the final image is completed and it would appear that "Calling ImageComplete user action" occurs, when I get an error. The strange thing is the error message suggests it's related to UCAC4, but I'm not using UCAC4 (I'm using USNO A2.0, in ACP, Maxim and Focusmax). Pinpoint works well in Maxim and the pointing images in ACP work well as you can see below. Have you seen this before?
