It has always been a problem using filters from different manufaturers. As we focus the guide camera parfocal with the main camera, once we changed filetrs, the guide camera would be out of focus. The solution we use to use was to focus the guide camera in between and hope for the best. Now we have a way of refocusing our OAG guide camera remotely. Of course the second advanatage is to use the focus motor to precisely focus our guide cameras.
