NGC1300 is a small galaxy lying in the middle of Eridanus meandering in the winter south sky.
The galaxy has a major axis of 6 arc minutes and 11th magnitude; it cannot be listed in observing objects with amateur telescopes because of its small size and darkness.
But NGC1300 is positioned at 2.3 degrees north of tau4 Eri with 4th magnitude so it's fairly easy to catch in the field of view.

A major characteristic of NGC1300 is being well-proportioned "bared" structure.
You can detect a clear bar stretched to east and west direction from a dimmed nucleus, and two spirals are coiled up from each tip of the bar.
Actually NGC1300 is fairly familiar with photographs taken by big telescopes, and often quoted as a typical example of Bared Galaxies.
