Reference image taken from DSS2 red

New image taken during exposure of the spectra. 15/03/2012 23:20 UT.
Refractor 0.13m, CCD KAF1603, L filter. Exposed29 x 2 mn. Super nova magnitude mesured at magV=13.8 with reference catalogue UCAC3 V band. This mesurement is not acurrate due to filter L for acquisiton that not match the reference mesurement in filter.
