Radio galaxy MRC 0406-244
This is another 'jittered' image of a 5x5 arcmin field, this time in a Ks (2.16 micron) filter and showing the radio galaxy MRC 0406-244 (redshift z = 2.4); it is identified by the arrow. North is at the top and East to the left; the scale is 0.29 arcsec/pixel and the FWHM of point sources in this re-combined set of 38 1-min exposures is about 0.7 arcsec. A K = 21 mag point source yields a signal-to-noise ratio of 4 within a 1.5 arcsec diameter aperture.
