NGC Nebula - Gulf of Mexico Region
with 10" f/3.9 Astrograph
Uploaded 8/23/23
| Here
is the southern half of NGC7000 - the North America Nebula in
Cygnus. We spent months taking the RGB data on this one, and
I dont think I can do much better than this with my 10 inch.
Recorded here are two of the "Holy Grails" of imaging
this subject. First, notice that the Gulf of Mexico is filled
in with a deep red emission glow, and overlaid with strings and
globules of dark nebula. The second feature to note that is very
rarely recorded is the yellow reflection nebula at the top of
the Gulf and surrounds a nice golden yellow star. You can see
it is quite a bit larger than just the central condensation.
This was surprising to see how extensive it is. Because we very
carfully G2V balanced this color shot, the main body of the nebula
itself is pink at the top, reds in the center and gradiates to
more orange at the bottom. All the star colors are also finely
calibrated to match thier spectral types. The surrounding sky
is so filled with dim red structured nebulosity that it is hard
to find any piece of dark sky. The impression one gets is that
NGC7000 is merely the brightest portion of a much more extensive
field of nebulosity. |
