Thanks Wavytone and ChrisM
Having read quite a lot of material (including the instruction manual found on line) I am fairly confident that I have mounted the telescope properly, albeit not on the wedge, and that there are no additional items affixed to the scope that I wouldn't expect e.g. different focus mechanism.
I have unlocked the mirror using the rear knob and can see the image moving in and out of focus when viewed directly on the prism without the eyepiece when I adjust the rear focus knob.
When I then fit the eyepiece however, all I can see is a completely white / hazy view that does not resemble anything, even something wildly out of focus, even at fairly low magnification e.g. 25mm.
It seems to me that either I have not fitted something e.g. some kind of extension tube to allow the eyepiece to resolve on the focal plane, or there is something more fundamental wrong that I am missing?
Thanks again for your help
