California Nebula – NGC 1499
California Nebula – NGC 1499
This is 20 hours on a very cool target with lots of mixed gas. NGC 1499 sits in the constellation Perseus, sort of out by itself, and is a bright emission nebula. It’s about 1,000 light years away. This target has bright Sulfur and Hydrogen emissions and very faint Oxygen to produce the colors represented here. It’s too faint to see with the naked eye, but was discovered in 1884.
