With the diagonal image focusing corrections, it is possible to obtain
uniform focus for the total projected image.
These corrections must be repeated for each colour. The Diagonal

then for blue.
First, be sure that the CRT projection angle is correctly adjusted,
otherwise it is not possible to obtain proper overall focus of the image.
