Description

NGC 6357 is an emission nebula in the constellation Scorpius, located just above the stinger of the scorpion at 8000 light years distance. This nebula is also called the "War and Peace" Nebula and includes the open cluster Pismis 24.

Bicolor image from red and blue frames (green = blue) taken on the island of La Palma in October 2015 on two consecutive evenings. Due to the late season, the nebula in the summer milky way was already low in the sky after dusk. Because of the narrow imaging window, I skipped the aquisition of the green channel. Two hours total integration time is of course very short. however, at declination -34 degrees, it is another impossible target from my usual site in Vienna!
