It's not. The parent post is inaccurate. The horsehead nebula is actually just off Orion's belt.
Yep. The Great Orion nebula, aka M42,
is a naked-eye object under any
reasonably un-light-polluted sky. I see it
well in 7x50 binoculars, and it's amazing in
my 115 mm telescope. I see 4 stars
in the Trapezium easily, and under good conditions
the nebula is faintly green.
It
photographs as pink, but that's another
story about the different spectral response
of the humn eye and colour film.
The Horsehead nebula, on the other hand, is
tough. I have photographs that show M42 clearly,
with a limiting magnitude about 7.5,
but not a hint of I434 and friends,
which is 3 degrees north of M42.
...laura, looking forward to seeing
NGC3372 aka the Eta Carinae nebula in
a few weeks
You can almost make out the words:
Be sure to drink your Ovaltine.
Am I the only one trying to find Magrathea from those photos?
