  Observing stars and satellites in optical wavelengths during the day (optical
daytime astronomy) has begun a resurgence of interest. The recent dramatic
dimming event of Betelgeuse has spurred interest in continuous monitoring of
the brightest variable stars, even when an object is only visible during the
day due to their proximity to the Sun. In addition, an exponential increase in
the number of satellites being launched into low Earth orbit in recent years
has driven an interest in optical daytime astronomy for the detection and
monitoring of satellites in space situational awareness (SSA) networks. In this
paper we explore the use of the Huntsman Telescope as an optical daytime
astronomy facility, by conducting an exploratory survey using a pathfinder
instrument. We find that an absolute photometric accuracy between 1 - 10% can
be achieved during the day, with a detection limit of V band 4.6 mag at midday
in sloan g and r wavelengths. In addition we characterise the daytime sky
brightness, colour and observing conditions in order to achieve the most
reliable and highest signal-to-noise observations within the limitations of the
bright sky background. We undertake a 7 month survey of the brightness of
Betelgeuse during the day and demonstrate that our results are in agreement
with measurements from other observatories. Finally we present our preliminary
results that demonstrate obtaining absolute photometric measurements of the
International Space Station during the day.
