The ASCOM standard allows for two types of focusers: absolute and relative. Since the FCUSB drives focus motors that have no encoders on them, it cannot be aware of the absolute position of the focuser. Thus the ASCOM driver for the FCUSB is written as a relative focuser. It sounds like ImagesPlus only allows for absolute focusers, I'm not sure why. You might lobby with Mike Unsold to add relative focuser capability to ImagesPlus, or give Nebulosity from www.stark-labs.com or some other software a try.

Hi Doug
Thanks for your reply.
I found some discussion on this at the Imageplus forum and Mike did leave a comment in 3/10 that he would try to " add support for the Shoestring FCUSB this summer when I
