Hi Bob,
I am using ACP Control in my observatory at New Mexico Skies. I have been imaging very successfully with ACP for 6 weeks with few errors excepting dome hardware problems. I have been doing flats using the Autoflats script and by checking dawn or dusk flats when doing a single target color series. These always worked perfectly until two days ago when I go this error. I have not changed any of the files excepting changing angle in defaultflat.txt. After getting this error I reloaded the Autoflats and defaultflat files, but got same error. It is possible that the techsupport team made a change that I am unaware of, but I have no way of knowing that. Can you shed some light on this error as I am dead in the water relative to flats. Imaging of targets continues to work great.
Using Paramount MEII, Planewave 17, Windows 10 Pro, 15 foot Technical Innovations at NMS.
Thanks for the help.
