Description:
NGC 7000 aka "The North American Nebula"
Perhaps discovered by William Herschel on October 24, 1786. Discovered by John Herschel before 1833.
This nebula is lying 3 degrees from bright Deneb, Alpha Cygni. Some people claim it may be visible to the naked eye under good, dark conditions, and a preferred object for amateur astrophotographers. The distance to the North America Nebula is estimated at 1,600 light years. The North America Nebula was perhaps detected by William Herschel who cataloged a "faint, extremely large, diffuse nebulosity" near its place under his catalog number H V.37. John Herschel definitely found it and cataloged it as h 2096 and later as GC 4621. It was first photographed by Max Wolf on December 12, 1890.
This image is as wide as I can go with my 80mm refractor and focal reducer. The field of view is limited by the size of the chip in my camera. However, I think it yeilds a nice level of detail in areas such as this. It also shows just how large this object is.
