This NAC image of Derain exposes a closer look at its well known collar of Low Reflectance Material (LRM). However, this image also offers a close enough look to see small hollows on the crater's floor. Due to the angle at which this image was taken, it is also easy to see the topography in this area of Mercury's surface.
