Here we present a first look at six galaxies observed for the Nearby Galaxy Showcase as part of the Early Release Observations acquired between August and November 2023. These targets, three dwarf galaxies...

Zusammenfassung:	is poised to make significant advances in the study of nearby galaxies in the Local Universe. Here we present a first look at six galaxies observed for the Nearby Galaxy Showcase as part of the Early Release Observations acquired between August and November 2023. These targets, three dwarf galaxies (Holmberg\,II, IC\,10, and NGC\,6822) and three spirals (IC\,342, NGC\,2403, and NGC\,6744), range in distance from about 0.5\,Mpc to 8.8\,Mpc. We first assess the surface brightness depths in the stacked images, and confirm previous estimates in 100\,arcsec$^2$ regions for Visible Camera (VIS) of $1 limits of $30.5$\ but find deeper than previous estimates for Near-Infrared Spectrometer and Photometer (NISP) with $1 By combining and into RGB images, we illustrate the large field of view (FoV) covered by a single reference observing sequence (ROS), together with exquisite detail on scales of $
