When you put your eye at the focal plane, you should be able to see all of the primary mirror reflected in the secondary. If not then the secondary isnt catching all of the light collected by the primary mirror and you have in effect a reduced aperture scope. Makes it harder to collimate too.
If your focal plane is high enough out of the focuser for all your eyepieces with some to spare, you might be able to pull the primary back a bit to help.
