Doesn't work, too many vibrations due to crew movement. What might work,
however, is to have it attached via tether using the gravitational gradient
to keep it in place. Maybe.

Assuming a Hubble-class instrument: Nope.

First: The vibrations will travel down the cable
from ISS to the telescope. There's nothing about
tidal effects to damp down transient vibrations
from crew movement... at least in a time frame
that would do the 'scope any good.

Second: ISS is a dirty place to hang around
outside for for long, if you're high-quality
optics, and is definitely in a low-rent
neiborhood orbit-wise
