First off... it's made by Zeiss not Leica. ;) Secondly, it is not uncommon for rangefinders to show the images not 100% alignedin the off-axis. It may be possible to get it better aligned, but opening it up to do that you risk throwing off the actual rangefinding alignment, which is far more critical. As long as your photos come out in focus when the images are basically aligned, then I wouldn't mess with it.
