|Notes:*||The "North America Nebula" is way to big for my field (about 31' x
46'). The 'Mexico' section of North America is sometime called "The
Wall", as it has a bright rim that shows well in narrow band H-Alpha
images. There are many images of this region of the Cygnus Milky Way on
the web (just Google NGC 7000), but
this image from the
website of Gimmi Ratto on
Band Imaging presents the North America / Pelican complex nicely.

NGC 7000 = North American Nebula = LBN 373 = Sh 2-117 20 59.3 +44 31 Size 120x100 17.5": at 100x and OIII filter appears very bright, extremely large (fills several fields), amazingly high contrast around the "Gulf" of Mexico and "Baja" region and to a lesser extent along the W and E coasts. Can trace around the entire border except for the "Canada" region which consists mostly of scattered star fields with weak nebulosity. The open cluster N6997 is easily picked out in the NE section. 8": bright, very large, sharp border and details around the "Gulf" section, "Southwest border" and "Baja region". Rich with faint stars. Easy naked-eye in dark sky. - by Steve GottliebHistorical Research Notes / Correction for NGC 7000
NGC 7000, the North America Nebula. WH saw only the brightest portion of this huge emission region, also the southern-most portion, ``Central America.'' JH was uncertain if his father had in fact seen the same nebulosity as he did, as WH's position is nearly a degree south of his own (I put the approximate center even further north than JH did). The most detailed part of WH's description makes JH's question even more relevant: ``... 7 or 8 arcmin long, 6 arcmin broad ...'' It's no wonder that WH's number ended up in the NGC followed by a question mark. There are a couple of minor mysteries about this nebula. WH claims only one observation of it in his published catalogue, as does JH in his. Yet, in GC, JH has the total number of observations by himself and his father as ``3.'' In addition, JH claims in his observation that the ``RA [is] that of V. 37 from working list, not being settled by the observation.'' However, the RA he quotes is nearly a minute of time larger than WH's published RA. The RA that JH adopts for GC is not quite a mean of the two values, but is closer to WH's original. I wonder if WH had another observation that somehow was skipped when it came time for publication. - Dr. Harold G. Corwin, Jr.
