Proper motions of stars are pre-galactic notions besides they contain
elements of the celestial sphere in position descriptions of external
galaxies.

Could someone translate this into standard English?

It's not easy but I'll give it a go:

a) So-called "proper motions" of stars are actually
an illusion caused by rotation of the Milky Way.

b) The Earth rotates through 360 degrees in a solar
day, not a sidereal day as astronomers think,
therefore the concept of right ascension as a
means of documenting the location of stars is
flawed.

As for the rest, your guess is as good as mine.
