"We will use the C11 in a two-year project to study, i.e. take astrophotos and measure/estimate redshifts of ~20 Abell clusters in the CfA2 Great wall. The red shifts are measured using a spectrograph with reflection grating having 1200 lines/mm. We are building the spectrograph now using a very general idea. The C 11 will also be used for ordinary astrophotography and observations of distant planetary nebula, one of them being the Footprint Nebula Mink 92 which we have been looking for for a long time. "
