Banard-150 Seahorse Nebula 26-Sep-24
Target: Banard-150 Seahorse Nebula
This is what's called a Dark Nebula. Instead of Hydrogen and Oxygen gases glowing as a reaction to certain wavelengths of light from stars, here the dusts and gases are dense enough to block visible light from stars behind them. This one's rightfully named the Seahorse Nebula, it is located in the Cepheus constellation about 1200 light years from Earth.
