NGC 247 (aka Caldwell 62) is a dwarf spiral galaxy in Cetus, and it is a member of the Sculptor Group, the nearest group of galaxies to our Local Group which includes the Milky Way.
NGC 247 has a slightly irregular shape on one end where the spiral arm has a hollowed out appearance on long-exposure photographs, resembling the shape of a neddle's eye. It is about the same size as NGC 253, but two magnitudes fainter. Recent measurements placed this galaxy about 11 million light-years away, about 1 million light-years closer than the estimated distance of NGC 253.
In the above wide field image is also revealed the rich background of this area which features a multitude of other galaxies, located a lot farther from our planet than NGC 247.

Why is this galaxy so discombobulated? Usually, galaxies this topsy-turvy result from a recent collision with a neighboring galaxy. Spiral galaxy NGC 1313, however, appears to be alone. Brightly lit with new and blue massive stars, star formation appears so rampant in NGC 1313 that it has been labeled a starburst galaxy. Strange features of NGC 1313 include that its spiral arms are lopsided and its rotational axis is not at the center of the nuclear bar. Pictured above, NGC 1313 spans about 50,000 light years and lies only about 15 million light years away toward the constellation of the Reticle (Reticulum). Continued numerical modeling of galaxies like NGC 1313 might shed some light on its unusual nature (text adapted from APOD).

NGC 6744 (also known as Caldwell 101) is an impressive spiral galaxy that lies about 30 million light-years away in the southern constellation of Pavo (the Peacock). But this view could almost be a picture postcard of our own Milky Way, taken and sent by an extragalactic friend, as this galaxy closely resembles our own.
We see NGC 6744 almost face-on, meaning we get a dramatic bird’s eye view of the galaxy’s structure. If we had the technology to escape the Milky Way and could look down on it from intergalactic space, this view is close to the one we would see — striking spiral arms wrapping around a dense, elongated nucleus and a dusty disk. There is even a distorted companion galaxy — NGC 6744A, seen here as a smudge to the upper left of NGC 6744, which is reminiscent of one of the Milky Way’s neighboring Magellanic Clouds.
One difference between NGC 6744 and the Milky Way is their size. While our galaxy is roughly 100,000 light-years across, the galaxy pictured here extends to almost twice this diameter. Nevertheless, NGC 6744 gives us a tantalizing sense of how a distant observer might see our own galactic home.
This dramatic object is one of the largest and nearest spiral galaxies. Although it has a brightness of about 60 billion Suns, its light spreads across a large area in the sky — about two-thirds the width of the Full Moon, making the galaxy appear as a hazy glow with a bright center through a small telescope. Still, it is one of the most beautiful objects in the southern sky, and it can be identified by amateur astronomers as an oval shape contrasting with a rich background of stars (text adapted from astronomy.com).
