  The BGO-OD experiment at the ELSA accelerator facility uses an energy tagged
bremsstrahlung photon beam to investigate the excitation structure of the
nucleon. The setup consists of a highly segmented BGO calorimeter surrounding
the target, with a particle tracking magnetic spectrometer at forward angles.
  BGO-OD is ideal for investigating low momentum transfer processes due to the
acceptance and high momentum resolution at forward angles. In particular, this
enables the investigation of strangeness photoproduction where t-channel
exchange mechanisms play an important role. This also allows access to low
momentum exchange kinematics where extended, molecular structure may manifest
in reaction mechanisms.
  First key results at low $t$ indicate a cusp-like structure in $K^+\Sigma^0$
photoproduction at $W = 1900$\,MeV, line shapes and differential cross sections
for $K^+\Lambda$(1405)$\rightarrow K^+\Sigma^0\pi^0$, and a peak structure in
$K^0_S\Sigma^0$ photoproduction. The peak in the $K^0_S\Sigma^0$ channel
appears consistent with meson-baryon generated states, where equivalent models
have been used to describe the $P_C$ pentaquark candidates in the heavy charmed
quark sector.
