This is a simple LSS/IMAGING programme, aimed to obtain low resolution
spectroscopy and broad band imaging for two helium flash objects, i.e.
V4334 (Sakurai's Object) and V605 Aql. The idea is to derive physical
parameters of the stellar remnants trhough atmosphere modelling and
optical properties of dust shells.

The high priority target is V4334, which should be around I=21.5.
V605 is fainter, V=23, and surrounded by a central nebula, which
will be possibly resolved in the FORS2 images.

Notice that the user writes in the finding charts that the position angle
should be chosen by the observer. Please, ignore this statement. Position
angle is set to 0.
