An R band image (FoV of 1.1′ × 1.1′) of the BL Lac object PKS 0048-097 obtained with NTT and SUSI (Melnick 1994) by Falomo (1996) that shows its close enviroment. The spiral galaxy G1 (panel b)) is the Mg II intervening system detected in the very blue part of the spectrum while the galaxy G2 is a foreground object with respect to the absorption. The panel a) in the figure shows a deconvolution of the image. The small object nearby PKS 0048-097 is most probably a background galaxy. Panel c) shows the image of galaxy G1 after the model subtraction, while panel d) reports the average radial brightness profile of galaxy G1.
