Conecuh National Forest
Dark Sky Observing Site
John Tatarchuk
I went down to the extremely dark Conecuh National
Forest Saturday 9/8 and Saturday 9/15. Using Google Earth, I have
at last located a large field where multiple observers can set up!
On 9/8, I had some high cirrus clouds to contend
with till about 10:30. However, once they cleared out, the sky was
spectacular. M33 was a clear naked eye object, and M31 stretched
for about 2 degrees naked eye. The Milky Way was extremely bright,
and had a very powdery, peppered look to it. The Gegenshein was visible
in northeastish Aquarius.
This was the first time I had gotten to do any
serious deep sky observing since April. I seemed a little rusty at
first, but soon got into stride. Objects like the North America Nebula,
Veil Nebula, and later, Horsehead Nebula were spectacular through the 18",
but the real meat of this observing session was the Abell galaxy clusters.
I observed five different extremely obscure Abell galaxy clusters, including
one at a distance of 1.9 billion light years. Towards dawn, Venus
startled me with its brightness, casting shadows.
I went back down to the Conecuh National Forest
on 9/15. This time I met up with Taras from the Mobile Astronomy
Club, who brought along his 10" Discovery dob and 4.5" RFT. We set
up in a fairly large, dirt field with pretty decent horizons that I had
found in Google Earth images. The sky proved very dark that night.
Not only was the Gegenshein visible, but around 1-2AM I noticed that the
even fainter zodiacal band was visible! The zodiacal band is a band
of light along the ecliptic that is caused by sunlight being scattered
by interplanetary dust. Unlike the zodiacal light, it is visible
at any time during the night, and it is also MUCH, MUCH fainter.
Pointing out the zodiacal band to Taras, he saw it too, saying "it looks
sorta like the Milky Way". Yea maybe, but 20 times fainter and only
about 10 degrees wide! It was incredible to look up and literally
see the plane of the solar system etched across the sky!
Anyway, the night proved to be one of the darkest
I have ever seen at the Conecuh National Forest. Overhead, it appeared
to be just as dark as West Texas. Unfortunately, I left my front
light baffle at home, and had to construct one on-site out of some sticks,
duck tape, and some black cloth. After I finished this, I got some
great views. I spent the time hunting Abell planetary nebulae, more
extremely obscure Abell Galaxy Clusters (I spotted 2-3 galaxies in one
that is 2.5 billion light years away!!!), and I even tracked down the supernova
remnant Cassiopeia A. Taras and I stayed all night till dawn.
I started packing up when I noticed that the morning light had made it
no longer possible to see the Horsehead Nebula without a filter.
Conecuh National Forest Dark
Sky Site
John Tatarchuk
I've been searching for the perfect Alabama dark
sky site for years. While I still haven't yet discovered the perfect
site, I've come very close.
Tom McGowan and I first scouted out the dark skies
of the Conecuh National Forest back in May 2005. We set up on the
side of a road, about 14 miles east of Brewton, Alabama (as the crow flies).
When the summer Milky Way reached meridian that night, we knew we had something
special. Since then I have scouted out two even darker sites closer
to the heart of the forest.
The skies at the Conecuh National Forest are very
dark- excluding the horizons which have some light pollution hugging them,
it's nearly impossible to tell you're not in West Texas. The faint
and elusive Gegenshein
is visible every night, and on a good night, the incredibly faint zodiacal
band (not to be confused with the immensely brighter zodiacal
light) is visible too. M33 is about to easy to see naked eye
as M31 from a magnitude 4.5 or 5 site. The Milky Way is incredible.
The Conecuh National Forest is located in extreme
south Alabama, east of the town of Brewton, Alabama, and southwest of Andalusia
and Opp. According to the light pollution maps, it's located in a
Bortle Scale 2 zone. While there are wide swaths of Bortle
Scale 2 areas in southwest and south-central Alabama, the Conecuh National
Forest is the only Bortle Scale 2 area that I have found that is located
on public lands. Below is a map of light pollution in central and
south Alabama, showing the normal AAS dark sky site (at Bortle Scale 4)
and the Conecuh National Forest.

Approximate driving times:
From Auburn: ~3-3.5 hrs, ~205 miles
From Montgomery: ~2.5- 2.75 hrs, ~155 miles
From Birmingham: ~3.5-4 hrs, ~230 miles

There are many ways to get to the Conecuh National Forest. The
exact site within the forest is located at:
31° 6' 40.24"N
86°42' 26.51"W
Let's assume that you're driving down I-65 South. At exit
77, south of Evergreen, turn left back over I-65 to the east on ALA 41
and drive 16 miles to downtown Brewton.

| At the railroad tracks in downtown Brewton, ALA 41 merges with US
29 North (Mildred St.).
You might want to reset your trip odometer as you cross the RR
tracks in Brewton. The following distances and mileages are based
on this as a starting point. The turn-off point to CNF is just past
"mile marker 25" on US 29N.
Continue 0.3 miles due east past the railroad tracks, over the bridge
into East Brewton, (now Forrest Ave.). At odometer reading 1.3, bear
left (east) where US 29 North diverges from ALA 41, and heads towards
Andalusia. |

| At about 9 miles out, you'll see CR 4 on the right. This is just
a landmark. Stay on US 29N. which is actually heading north
here.

At about mile 12, US 29N is heading east.

At about mile 20, (just past "Brooklyn Road.) you'll cross the "McGowan
Bridge". Thanks Tom!

Just beyond mile 24 you'll pass "Mason Cemetery Road", and be heading
almost due east.

Near mile 24.5, you'll see CR 11 (Dixie Highway) intersecting from the
south. Stay on US 29N.
Near mile 25.0, pass "Dixie School Road." from the north (where the
"US 29" marker is on the above image). Start slowing down and put
on your right turn signal.
Near mile 25.2 Open fields, dwellings, and farm buildings
on the right changes to forest.
At about mile 25.4 TURN RIGHT (south) on what we think is "Forestry
Rd. 311B" but it may not be marked. This sandy road is well hidden
in the trees. You'll pass a cotton field on the right shortly after
your turn.
If you find yourself entering Covington County, you just missed the
turn-off. Turn around and try again.
It's another 3.2 circuitous miles to the observing field. Your
odometer should now be about 28.6 miles.
BE CAREFUL: The field is set a bit off the road, and in the dark,
it could be missed.
The observing field is a cleared, flat, very sandy field. There
are a few weeds growing in it, but very little grass. Because of
the extremely sandy soil, it's dry and free of mud. Make sure to
bring a tarp to set the scope up on! It takes a vehicle with a decently
high suspension, such as a small truck or SUV, to directly drive out into
the field, as there is a steepish drop off right where you pull off the
road. No fear though, if you have a small car with a low suspension,
there is a place where you can park. However, you will have to transport
your equipment from this parking spot about 75 yards out into the field. |

| Driving back from the Conecuh National Forest can be tough after staying
up all night observing. I recommend a 1-2 hour nap after the observing
session is over. Dark skies aren't worth dying for. |
