Description

The Lobster nebula is another object located in the southern Milky Way imaged during my vacation in La Palma (Canary Islands) using my little SW 130/650 Newtonian reflector. In October, this part of the Milky Way is already low on the horizon, leaving only two hours of darkness for imaging before setting.

NGC 6357 in the constellation of the Scorpion houses the open star cluster Pismis 24. The red nebula results from the emission of ionized hydrogen gas triggered by embedded young stars. The nebula’s complex shapes are caused by interactions between interstellar winds, radiation pressures, magnetic fields and gravity. NGC 6357 is about 400 light-years in diameter and lies about 8.000 light-years away.
