Coliln, first off, beautiful shot of Leo! Nice flat field, tastefully
processed!

The shot of Leo, in the highest resolution image you posted, seems to show
one of two symptoms:
a) every bright star mysteriously has a companion in the exact same
orientation or,
b) you have the dreaded nose/foot binary syndrome.

Is it me or do all the bright stars have a tiny secondary?

Don't know about the other shot - film buckling would be my first guess but
it isn't that common in 35mm cameras unless this was your second shot of the
night and you had the camera out of use for awhile. The second shot would be
the frame that was half wrapped on the rollers. Scientific Wild Assed Guess
as they say.
