LDN 1235 Shark Nebula Zoom View
| Description | The Shark Nebula, also known as LDN 1235, is a faint cloud of interstellar gas and dust located in the constellation Cepheus. This nebula is not visible to the naked eye, and it is difficult to observe even with binoculars or telescopes. The best viewing time is between May and December when the constellation Cepheus is highest in the sky. Due to its faintness, the Shark Nebula poses a significant challenge for imaging, especially from urban areas. It also contains smaller dark nebulae, such as Lynds Dark Nebula 1235 and Van den Bergh 149 and 150. The Shark Nebula is positioned between the constellations Draco and Cassiopeia. |
