Offset gunsite in German WW II Fighters - why ?

Cockpit photographs of the Bf-109 and the Fw-190 show the gunsite offset to the right. These photos also seem to indicate that the pilot seat was on the aircraft centerline and not offset.
I can't figure out why they did this. I'm sure they had a reason.
Can anybody explain this ?
Thanks, and Merry Christmas
