  We describe the design and commissioning of a simple prototype, low-cost
10$\mu$m imaging instrument. The system is built using commercially available
components including an uncooled microbolometer array as a detector. The
incorporation of adjustable germanium reimaging optics rescale the image to the
appropriate plate scale for the 2-m diameter Liverpool Telescope. From
observations of bright solar system and stellar sources, we demonstrate a plate
scale of 0.75$^{\prime\prime}$ per pixel and confirm the optical design allows
diffraction limited imaging. We record a $\sim$ 10$\%$ photometric stability
due to sky variability. We measure a $3 \sigma$ sensitivity of $7 \times
10^{3}$ Jy for a single, $\sim$ 0.11 second exposure. This corresponds to a
sensitivity limit of $3 \times 10^{2}$ Jy for a 60 second total integration. We
present an example science case from observations of the 2019 Jan total lunar
eclipse and show that the system can detect and measure the anomalous cooling
rate associated with the features Bellot and Langrenus during eclipse.
