SEPTEMBER 2015 OBSERVERS CHALLENGE – NGC-7000-1

The following pencil sketch was made using a blank 5 x 8 notecard with a 10-inch Newtonian reflector telescope.  The observation, notes and sketch were made from my moderately light polluted backyard, located in the Foothills of North Carolina.    roger ivester

NGC 7000 “The North America Nebula” Cygnus
Date: September 17, 2015
Conditions: Fair seeing with a NELM of 5.0

Telescope: 10-inch f/4.5 Newtonian Reflector
Sketch: 36x with an O-III Filter
FOV: 1.8º

A dark sky is preferred for this very large emission nebula, however, I’ve observed the North American to a satisfactory level on many occasions from my moderately light polluted backyard using my 10-inch reflector. An O-lll filter is essential when observing this object.

I found it necessary to place a commercial black cloth to shield ambient light from entering my eye, due to several unshielded streetlights in relative close proximity. After covering my head, the difference was amazing, as the outline of the nebula became much sharper and brighter.

The dark region known as “the Gulf of Mexico” is the most noticeable feature. At 36x and with a FOV of 1.8º much of the North American shape is visible. Open star cluster, NGC 6997, a sprinkling of faint stars is located in the “Ohio” region. If using an O-III or UHC filter while observing the North American Nebula, be sure to remove when observing this cluster.

IC 5070, “The Pelican Nebula” lies just to the west of NGC 7000. The Pelican was fairly easy to see, appearing as a large very faint diffuse region without any definite shape.   Roger Ivester
