To study the small-scale dynamic processes of magneto-convection in the solar photosphere in more detail than currently achieveable, not only the spatial resolution has to be increased, but also the information content of observations. In order to do so, several wavelengths and spectral lines must be observed simultaneously. This is often achieved by coordinated campaigns at several telescopes with different post-focus instrumentation. The German Vacuum Tower Telescope (VTT) on Tenerife offers the possibility to operate several dedicated instruments spectrometers, polarimeters, imaging systems at the same time. We describe some of the possible combinations of post-focus instruments, and present examples of multi-wavelength data obtained recently.
