Focal plane filter wheel

This has 8 positions, each of which can hold a circular filter up to 125 mm in diameter. The filters available for use with TAURUS-2 are listed in viii. The filters can be tilted by up to 10 degrees; this has the effect of shifting the central wavelength of interference filters to the blue (see section viii).
