NGC 1300 is an 11th magnitude barred spiral galaxy in the constellation Eridanus. It was discovered by John Herschel in 1835, and is often touted as the most spectacular example of a barred spiral galaxy.
This galaxy is rather faint even in larger instruments. The central bar extends 6.5' E-W, with faint but distinct spiral arms attached to each end, making a reverse S-shaped spiral. The arm attached to the west end curves north of the bar to the east, and the arm attached to the east end curves south of the bar to the west. A faint knot or star lies just NE of the bar's prominent 1' diameter core.
NGC 1300 is about 70 million light-years away and 110,000 light-years across - just slightly larger than the Milky Way. Unlike other spiral galaxies, including our own, NGC 1300 is not presently known to have a massive central black hole.
In the Hubble image above, blue and red supergiant stars, star clusters, and star-forming regions are well resolved across the spiral arms, and dust lanes trace out fine structures in the disk and bar. On close inspection, the nucleus of this classic barred spiral itself shows a remarkable region of spiral structure about 3,300 light-years across. handful of background galaxies, that may be (or more) than 5 times as distant and are seen even through the densest regions of NGC 1300.
