List of star hops |
This nebula gets its name from its
curious resemblance to the shape of the continent. On a dark night, it can be seen with the naked eye as a hazy patch in the Milky Way, several times the diameter of the Moon. It consists of vast expanses of
glowing hydrogen gas. The nebula is
in a dense section of the Milky Way. A small open cluster that can be seen in roughly the "Great Lakes" region of the nebula is NGC 6996. |

Directions: Start by finding the Summer Triangle, which consists of the three of the brightest stars in the sky--Vega, Deneb, and Altair. The Summer Triangle is high overhead throughout the summer, and it sinks lower in the west as fall progresses. For this star hop, start from Deneb, the first-magnitude star that forms the tail of Cygnus, the swan (or if you visualize the brightest stars of Cygnus as a cross shape, Deneb is at the top of the cross). |

From Deneb, the North America Nebula is just about 3 degrees to the east. It may be visible to the naked eye, and is a nice sight through binoculars on a dark night. With a telescope, it is best viewed with a wide-field eyepiece. There are faint patches of nebulosity and star clouds visible throughout the area. See if you can spot the dark nebula that represents the Gulf of Mexico. |
