The Taurus Tunable Filter (TTF) is a pair of tunable narrowband interference filters covering 3700-6500 Å (blue 'arm') and 6500-9600 Å (red 'arm'). The TTF offers monochromatic imaging at the cassegrain foci of both the Anglo-Australian and William Herschel Telescopes, with an adjustable passband of between 6 and 60 Å. In addition, frequency switching with the TTF can be synchronized with movement of charge (charge shuffling) on the CCD which has important applications to many astrophysical problems. Here we review the different modes of TTF and suggest their use for narrowband imaging.
