PKS0521-36 is a V=14.4 galaxy hosting a V approx 16 BL Lac and an optical synchrotron jet V approx 21.0 starting 1.7arcsec from the nucleus and extending to 6arcsec. The variety of complex structure (galaxy, nucleus, jet), availability of a 0.3arcsec resolution VLA map, ground based NTT imaging and challenge of resolving faint structure in both the galaxy and jet next to the bright nucleus suggest this would be an excellent target for early science assesment. Simulations indicate a nuclear count rate of about 4/sec (assuming 15% of the light in the psf core) and with the jet 100times fainter we should accumulate around 15000 counts in the jet, or about 20 per resolution element peak. Accurate target acquisition capability is an essential prerequisite. Accurate psf images through target filters are essential.
