Photo description / processing

NGC 247 (Needle's Eye or Claw) is located at a distance of 11.8 million light-years, with a diameter of about 70 thousand light-years. The galaxy's angular size is 19.2x5.5 arc minutes. NGC 247 has a void clearly visible in photographs, which is why it is called the Needle's Eye galaxy. It is located in the constellation Cetus. 

In Adygea (44th latitude), it does not rise above 25 degrees above the horizon. Nearby (to the right and up) is a group of 4 galaxies called Burbidge's Chain. This group is located at a distance of about 350 million light-years from us, which is almost 30 times farther than NGC 247.
