NGC 6207


NGC 6207 is a spiral galaxy located in the constellation Hercules. It is designated as SAc in the galaxy morphological classification scheme and was discovered by William Herschel on 16 May 1787. NGC 6207 is located at about 30 million light-years from Earth, and its approximate size is around 36,000 light-years across. In the sky, it is located near the globular cluster Messier 13.

Visibility

The galaxy has an approximate brightness of about 11.5, making it extremely faint and would require a telescope with an aperture of around 4 inches at the minimum to get a faint shape. Because of its low surface brightness, you would need a telescope of around 6-8 inches would get more detail and clarity.

Observation History

NGC 6207 was discovered by William Herschel on May 16, 1787. It was added onto his extensive list of nebulae as NGC 6207

Properties

It has a diameter measured through the D25 standard - the isophote where the surface brightness of the galaxy reaches 25 mag/arcsec2, to be about 11.03 kiloparsecs, making it roughly 36% of the Milky way.

Structure

The galaxy display's a classic spiral structure, and can be defined as "Small, oval galaxy, evenly bright. Nucleus visible". It also hosts multiple H II regions. This suggests that despite being a relatively quiet galaxy, still hosts on-going star formation activity.
