∞ focus at ∞ distance = out of focus?

In attempting to take some moon pictures I noticed something wacky - on my manual reflex/mirror lens I must focus WAY pre-infinity to get the moon in focus. It's the moon - it's infinite distance right? Is this normal or is there something wrong with the lens and/or pairing of lens and camera?
Camera: Nikon d90 (APS-C sensor, lens is film-era)
Lens: (super old) Osawa 650mm mirror lens
