Euclid RGB images of the four previously known dwarf satellites from Carlsten et al. (2022) that fall in the field of view of the Euclid image of NGC 6744. Red is given by HE, green by YE, and blue by IE. The sizes of the images are 250ʺ, 150ʺ, 120ʺ, and 120ʺ on a side, from left to right; north is up, east to the left. With the exception of NGC 6744A, a well-known dwarf satellite lying along spiral arms to the northwest of the nucleus, name designations are from Carlsten et al. (2022). In the cut-out of dw1906m6357 (third panel from the left), there are also two blue circular structures that are dichroic ghost artifacts (see also Fig. 1).
