It took me a full year off & on trying to nut this issue out. I almost gave up & flogged the telescope on eBay as faulty. It wasn't until I started to think of the problem being like a camera lens aperture & how the depth of field from f16 to f2.8 changes the focal length that made the penny drop and gave me a solution. I was of the belief that the primary & secondary mirror distant didn't matter because of the focus knob position, how wrong I was...Anyway I have a greater understanding now of how a Reflector works.
