The Huntsman Telescope
  The Huntsman Telescope, located at Siding Spring Observatory in Australia, is
a system of ten telephoto Canon lenses designed for low surface brightness
imaging in the Southern sky. Based upon the Dragonfly Telephoto Array, the
refractive lens-based system provides an obstruction free optical path, which
reduces the number of scattering surfaces and allows easier access to lower
surface brightness levels.
  In this proceeding, we present an analysis of the impact of flat fielding
uncertainty on the limiting low surface brightness levels. We show that a
fairly standard set of flat-field data can be well-characterised to a
$\sim0.1\%$ level. This corresponds to a 5-$\sigma$ lower limit of $\sim33$
magnitude per arcsecond$^2$, which means that flat fielding is not likely going
to set Huntsman's low surface brightness limit.
  We also present early results of an exoplanet transient mode for Huntsman
where all lenses work together to detect subtle variations in the luminosity of
relatively bright $V=8-12$ magnitude stars. High-precision exoplanet imaging is
ultimately limited by systematic uncertainties, so we anticipate multiple
lenses will help to mitigate issues related to pixel-to-pixel and intra-pixel
sensitivity variations. Our initial results show we can easily get $\sim0.4\%$
photometric precision with a single, defocused lens.
