  When considered as a Deligne-Lusztig variety, the Drinfeld half space
$\Omega_V$ over a finite field $k$ has a compactification whose boundary
divisor is normal crossing and which can be obtained by successively blowing-up
projective space along linear subspaces. Pink and Schieder (2014) have
introduced a new compactification of $\Omega_V$ whose strata of the boundary
are glued together in a way dual to the way they are for the tautological
compactification by projective space. We show that by applying an analogous
sequence of blow-ups to this new compactification we arrive at the
compactification by Deligne and Lusztig as well. Moreover, we compute for each
of these three compactifications the stabilizers of $\bar{k}$-valued points
under the canonical $\mathrm{PGL}(V)$-action. We find that in each case the
stratification can be recovered from the unipotent radicals of these
stabilizers.
