Images for one night per observing epoch in 2021, where north is up, east to the left, and the flux normalized to S29. For each night, we performed ten imaging runs with varying random seeds and then picked the cleanest result with the highest degree of consistency over the full year. Images are computed as mean over all samples in the chosen run, centered on Sgr A*, and smoothed with a Gaussian of 1.6 mas standard deviation, whose FWHM is indicated in the bottom left corner. Sgr A* varies in flux, and we here show its mean brightness over all exposures and polarization states. On each image, we overdraw the orbits of S29 and S55 and the labels of all identified sources to give a better orientation. We note that due to the large dynamical range and the logarithmic color scaling, sources appear more widespread.
