LSS in the outskirts of an edge-on galaxy parallel to its major axis to look for Halpha emission. Four pointings (SeqA to D), two OBs each. ACQUISITION: there is no specific object to be put in the slit, as the aim of the observations is the diffuse emission. In fact, this is point-and-shoot spectroscopy and no offsets should be made compared to the preset position. In practice, click anywhere on the acquisition image and *do not* apply the offsets. The user has explicitely acknowledged that the resulting pointing accuracy is good enough for his purposes.
