  We report on highlight results on celestial sources observed in the high
energy band (>20 keV) with BeppoSAX. In particular we review the spectral
properties of sources that belong to different classes of objects, i.e. stellar
coronae (Algol), supernova remnants (Cas A), low mass X-ray binaries (Cygnus
X-2 and the X-ray burster GS1826-238), black hole candidates (Cygnus X-1) and
Active Galactic Nuclei (Mkn 3). We detect, for the first time, the broad-band
spectrum of a stellar corona up to 100 keV; for Cas A we report upper limits to
the ^44Ti line intensities that are lower than those available to date; for Cyg
X-2 we report the evidence of a high energy component; we report a clear
detection of a broad Fe K line feature from Cygnus X-1 in soft state and during
its transition to hard state; Mkn 3 is one of several Seyfert 2 galaxies
detected with BeppoSAX at high energies, for which Compton scattering process
is important.
