Two CCD cameras (pco.4000 and pco.sensicam) can be used in the BIC of the GFPI depending on the availability of the GREGOR/VTT facility cameras. Three interference filters (Ca II H λ396.8 nm, G-band λ430.7 nm, and blue continuum λ450.8 nm) are available. Recently, MPS contributed a 0.1-nanometer-wide Ca II H λ396.8 nm interference filter of the Sunrise mission. The maximum FOV of the pco.4000 CCD cameras is limited to 75″ × 93″ (2160 × 2672 pixel) because of dichroic pentaprism splitting the light between GFPI and BIC. The FOV of the pco.sensicam CCD camera is much smaller 34″ × 26″ (1376 × 1040 pixel) but the data acquisition rate is much higher (eight vs. three frames per second). However, in both cases post-facto image restoration is feasible (Knox-Thompson, speckle masking imaging, and multi-frame blind deconvolution)
