Lobster Nebula is a HII region (giant cloud of excited hydrogen gas) located in the constellation Scorpius. The nebula rises only 8° above the horizon in Central Europe, which means, it is submerged in light pollution caused by nearby towns, villages, or cities. The situation is completely different on the Canary Islands, where the nebula rises 27° above the horizon. Therefore, this nebula was the primary target of my expedition to Fuerteventura. Unfortunately, the weather didn’t cooperate and strong winds caused bad seeing and didn’t allow me to capture more frames. So, next time it will be better.
