Due to my unfortunately very limited knowledge of English, I may not have understood what the actual problem is. However, I dare to say that I have solved to a large extent the cause of my ever-painful neck-breaks and twisting after coming to frame with my NIKON D3000, by sticking a small prism on a frame with silicone, which I attach to the camera’s viewfinder. Certainly not the best, nor is it ‘Columbus egg’. I just avoided a perhaps unnecessary expense, like so many others that amateur astronomers make.
If I have not understood what the underlying problem is, please excuse me.
