Tip-tilt effect on the apparent magnitude of S2 in the images reconstructed by GRAVITY centred on the Galactic centre. A 50 mas tip-tilt allows keeping the apparent magnitude of S2 above the current sensitivity threshold of K = 18 in the images reconstructed from GRAVITY data, up to a separation of ∼100 mas.
