Direct comparison of the J-band imaging data obtained using the CAHA3.5/Omega2000 and the WST/3KK instruments. Note the clearer signal of the faint sources close to the centre, as well as the better seeing when comparing the stellar sources. For a quantitative comparison of the imaging data, please see Table D.2. One should consider the fact that this target had the worst image quality in all the CAHA run, and the best in the WST run.
