Sinus Iridum. The north of Moon through a telescope.

It is not the first time we talk about "Gulf of rainbows" or Sinus Iridum. This great golf, Mare Imbrium basin full of lava, has 236 km. The wall forming the crescent-shaped bay is called Montes Jura.

Sinus Iridum is very popular among the "lunatics" because of its shape and because it is in stark contrast to Mare Imbrium, which is dark and the two features combined make the bay to stand out as it is observed even by a ordinary binoculars.
Sinus Iridum's name was given by Giovanni Riccioli.
