Spectroheliograms in the OAUC (Coimbra, Portugal) have been photographed in the spectral line of Ca II continuously since 1926 and, since 1990, spectroheliograms in H-alpha have been photographed as well. Since 2007, all the spectroheliograms have been recorded using a CCD camera. On the data recorded in 2010 we demonstrate the good quality of spectroheliograms taken during standard observing conditions, influence of clouds, and the effects introduced by a visualization filter.
