NGC 247 is an Intermediate or Dwarf spiral galaxy about 11 million light years away in
the constellation Cetus. It is a member of the Sculptor Group of galaxies, one of several
that are gravitationally bound to the Sculptor Galaxy (NGC 253). This is one of the
nearest groups of galaxies to the Milky Way. This is a large (21.4x6.9 arc minutes),
bright (mag 9.9), and detailed galaxy but it lies low in the sky for my latitude, reaching a
maximum elevation of only 30 degrees. This makes it difficult to get a quality image
because the low elevation means that my telescope will be peering through a huge
amount of light-scattering atmosphere, dimming and blurring the image. That said, the
size and detail in this object demands that we give it a try.
