Rik ter Horst (ASTRON) spent one week in Sutherland to test the optics of MeerLICHT with on-sky observations and to align the primary mirror of MeerLICHT to perfection. This has resulted in sharp, round stellar images across the entire 2.7 square degree field of view of MeerLICHT [only a small part of the full frame is shown here].
