Thanks Matty

I looked at some of the older threads and picked up on the advantages of monochrome (plus filter wheels) compared with the DBK in terms of resolution. My truss is now set so that a CCD camera (MallinCam) can be focused when the focuser (Feathertouch) is almost fully racked in, and the eyepieces when almost fully racked out. My concern is that adding a filter wheel will mean that the arrangement will not accommodate the eyepieces/MallinCam/DMK on the same set of poles, as I will need to rack the focuser in a further 15-20mm beyond where is it now in focus with the webcam and I don't have that amount of travel left. Is this correct?
