AB: Photometric, spectroscopic and polarimetric observations in the He 1083 nm line provide important diagnostic information on the structure and dynamics of the chromosphere and the overlying corona. We will describe an imaging instrument, designed to observe the chromospheric He 1083 line, based on a helium magneto-optical filter. The narrow pass-bands and high throughput of the filter make it ideal for making high cadence observations in support of studies of wave propagation in the chromosphere. We will describe the operation of the instrument and present preliminary photometric observations.
