Around the western edge of Eridanus, a tiny spiral of NGC1084 is lying near the border to Cetus. You can use Mira as a guide star tracing toward SE about 8 degrees.
The galaxy has a long axis of 3 arc minutes and a brightness of 11th magnitude, it's very minor one but this image shows you an unexpectedly good-proportioned face-on galaxy. It seems like a shrunken M33 in Triangulum.
