Instrument Specifications

A wide field imager is required, since enough comparison stars have to be within the frames. The instrument is equipped with a filter wheel that holds two specifically designed filters. The red filter resembles the spectral response curve of the TESS detector as closely as possible. The blue filter covers the wavelength regime shortwards of the red filter to provide color information. WFTP features a modular and lightweight design so that it can be brought to and operated on small telescopes. This, however, does not prevent its use on larger telescopes.
