This is a run which includes both LSS (600B+600R) and Imaging (U,B,R) 
of the cooling flow galaxy Abell 1795. The project is meant to obtain
accurate line ratios of the typical HII regions in order to explore
the excitation mechanism and to detect dust.
The imaging part will be used to search for star-forming regions.

The spectroscopy OBs use blind offsets with respect to a reference star,
and take two exposures per grism, with telescope 2 offsets along the
slit.
The imaging part (1 OB) is done using an occulting mask in order to avoid
strong saturation effects from a star close to the target. The same OB 
includes three exposure, each of them using a different filter (U,B,R)

Note that the target, due to its coordinates, does never get an airmass
lower than 1.5.
