Marc,
Low QE is the main problem.
Other issues is the type of optical system used and atmospheric conditions.
Refractors or reflectors that use corrector lenses will further reduce performance.
Long wave UV is much more sensitive to atmospheric extinction and reduced transparency than the visible spectrum.
