The California Nebula (Also known NGC 1499 or Sh2-220) is an emission nebula located in the constellation Perseus. Its name comes from its resemblance to the outline of the US State of California in long exposure photographs.

The California Nebula (NGC 1499, Sh2-220) is a large emission nebula in Perseus, powered by the nearby O7 star, Menkib. This image captures the strong hydrogen and sulfur gas emissions of the nebula...

2022年7月6日 · The nebula has the designations NGC 1499 in the New General Catalogue and Sharpless 220 (Sh2-220) in the Sharpless catalogue of emission nebulae. The California Nebula stretches about 100 light years across.

Sh2-220 is a large emission nebulae that I captured here with narrowband filters, a monochrome camera, and a camera lens with a focal length of 200mm. It was all shot from my light polluted backyard and front yard in Newark, DE.

2021年10月17日 · This is an image of the California Nebula (NGC 1499, LBN 756, Sh2-220) central area. It also encompasses part of the large area of nebulosity (LBN 752 - faintest LBN class) which is about twice as large as NGC 1499. The California Nebula's emission is energized by Menkhib (Xi Persei).

The California Nebula (NGC 1499/Sh2-220) is an emission nebula located in the constellation Perseus. Its name comes from its resemblance to the outline of the US State of California in long exposure photographs.

This is the so-called California Nebula (catalogued as NGC 1499 or Sh2-220), an emission nebula located in the constellation of Perseus whose name derives from its resemblance to the profile of the US state of California in long exposure photographs.

2022年12月24日 · The California Nebula (NGC 1499/Sh2-220) is an emission nebula located in the constellation Perseus. Its name comes from its resemblance to the outline of the US State of California in long exposure photographs. The brighter section is almost 2.5° long on the sky and, because of its very low surface brightness, it is extremely difficult to observe

2023年2月22日 · It can be observed with a Hα filter (isolates the Hα line at 656 nm) or Hβ filter (isolates the Hβ line at 486 nm) in a rich-field telescope under dark skies. It lies at a distance …
