LOOKING
UP OBSERVATORY
BACKYARD ASTRONOMY
USING
seat of the pants technology
last updated 30 September 2004
Pictured
on a typical sub zero
winters night in Maine, I pursue my favorite pastime, viewing the
heavens and taking images of the various objects that it holds.
My interest in this activity didn't come until a few years ago and I
place most of the blame on this character,
WAYNE,
my friend and aspiring
astrophotographer. For more
astrophotos you can visit his web site. Pictures and list of my
equipment will be added at a
later time. If you have any questions or comments e-mail

Adjust your monitor so that
each square is a distinct shade. This is necessary to ensure
that many of the details will be seen.
What
is a light year? It is
the
distance in miles that light travels in 1 year in a vacuum such as
space. The speed of light is approximately 186,280 miles per second. So
in a year light travels approximately 5,874,526,080,000 miles or 5.88
trillion.
Personal note; One the
things that fascinates me about taking these images is considering the
distance the light has traveled and for the time it has traveled I am
actually taking a picture of the past. These objects are
constantly changing and who knows what they actually look like today.
Comet
C2001 Q4 NEAT Comets are large masses of frozen gas (ice
balls) combined with
dust and rock. It's possible that this may be the first time this comet
has ever visited our solar system.
First discovered in 2001 it passed within 30
million miles of earth during May 2004. At it's brightest it was
visible to the unaided eye for anyone knowing where to look. As a
comet get
closer to the sun radiation causes the gases to heat up and shed
material creating the tail. This 2 minute image was taken
on
5/17/2004 using
a TEC
140, CG11 and Waynes ST2000 CCD camera.
M42
Great Orion Nebula. Located 1,500 light years away in the
constellation of Orion. Nebulae are regions of space where there
are very
large clouds of dust and gas. Light from nearby stars is reflected on
the
dust (reflection). In
other nebulae the
radiation and heat from the stars, cause the gases in the space
around them to emit
their own ionized glow (emission). Some, like M42 are visible to the
unaided eye. When a
nebula exhibits both types of nebulosity it is known as a, diffuse
nebula. The red
areas
are attributed to emission and blue to reflection. Many nebulae
are
birthing regions for new stars but not all are star forming. This
three minute image was taken
on 01/10/04 using a TEC 140 scope, CG11 mount and a Nikon 4500
camera with a William Optics 24mm EP.
Jupitor Image taken on 12/27/03 using the TEC 140 , CG11, and
Nikon Coolpix 995 with a 14mm Scopetronics EP. The image is made
from 11 x 1/8th second images.
Saturn
Image was taken on 12/20/03 using the TEC 140, CG11 mount, Nikon
Coolpix
995
with a 18mm Scopetronics EP. The image is made from 12 X 1/2 second
images. I had some
processing assistance from another backyarder, Forrest Egan.
Thanks Forrest.
M51 Whirlpool Galaxy So named for it's famous spiral arms and
interaction with a smaller companion galaxy. This face on
galaxy is located in the constellation of Canes Venatici and is
approximately 37 million lights years distant. If
you were to look at the Big Dipper this galaxy is situated near the
last star on the handle. In the future I plan to expand with more
galaxy
images. This 2 minute image was taken on 05/11/04 using
a TEC
140 , CG11 and a SBIG ST237 camera. This was my very first RGB
and LRGB image ever with my new used camera.
M13 The great cluster in Hercules. In some areas of space there are
groups or clusters of stars . M13 has over 100,000 stars in its
cluster. It is located in the constellation of Hercules and is over
20,000 light years distant. In 1974 a radio message
was sent towards this cluster in hopes that there would be someone to
hear
it. Even if it works, it will take 50,000 years to hear the reply.
This 1 minute LRGB image was
taken on 05/19/04 using the TEC 140, CG11 and
ST2000 camera.
M57
The Ring Nebula. This is a planetary nebula located in the
constellation Lyra. This type of nebula is formed when a red giant star
blows off (explodes)
it outer layers into space. These expelled layers can become visible
and often will have a round or ring shape although other shapes may
form. This 1 minute image was taken on 05/19/04. As can be
seen from the image there are areas of reflection and
emission nebulosity in this type of nebula.
M20
Trifid Nebula Located approximately 5,000 light
years away in the constellation of Sagittarius. Named because the
dark dust lanes that cause the nebula to be broken into
three separate parts. The 5 minute image was re-taken
on 8/20/04. Image taken with TEC 140, CG11, and
ST237.
M8
Hourglass Nebula Also called the Lagoon Nebula,
was first discovered in 1680 and latter cataloged by Charles Messier in
1764. This is a faint, extremely large nebula that, with a longer
exposure, would show that it is in fact much larger than the frame of
the picture. This image also taken on 6/13/04 was actually a
fluke of the night. I happened across it as I was panning the sky with
a wide field, lower power magnification. When I took the
image I had no idea on what it was I was imaging and had to later
research and identify the new object. Image taken with TEC
140, CG11 and ST237.
M27 Dumbbell Nebula This object is
located 1,200 light years distant in the constellation of Vulpecula. It
was first discovered by Messier in 1764. Another example of
planetary nebula similar to M57 except, instead of a ring
shape, this has formed a dumbbell shape. I have wondered if the
dumbbell shape is due to an edge on view instead of face
on. Image taken with TEC 140, CG11 and ST237. Image taken 6/23/04
NGC7635
Bubble Nebula This emission nebula is approximately 11,000
light years distant in the constellation of Cassiopeia. The bubble of
glowing red hydrogen gas is caused by stellar winds generated by the
intensity of the hot stars in the center of the bubble.
This is another object that I will be going back to. There is much more
nebulosity that can captured with a longer image. This LRGB
image of 25x15x15x15 was taken using the TEC 140 and ST237. All images
are 5
minute exposures processed with CCD soft. Image
taken 8/2/04.
M17
This nebula has been given a number of common names over the years such
as Omega, Horseshoe, Lobster and Swan. It resides in the constellation
of Sagittarius about 5,000 light years away. This hydrogen emission
nebula is estimated to be several million degrees hot. The intensity is
caused by young massive stars that reside inside the extreme dust
region. The dust being so thick and dark that it hides the objects that
cause it to glow. Image taken 8/9/04 using the ST237, TEC 140 and
CG11.
IC 5146 This beautiful nebula is commonly known as
the Cocoon. It's located in the constellation of Cygnus about 4,000
light years away. Much of the nebulosity is generated by the
large central star. This star is thought to be about 100,000
years old compared to our sun which is believed to be about 5
billion years old. The image is my first taken with my newly
acquired ST2000XM and is a LRGB of 30x10x10x10 minute exposures.
Taken on 8/22/04.
M45 popularly known as The Seven Sisters or " Pleiades". This
bright star cluster can be seen with the unaided eye during the winter
months. This image captures three of the Sisters, Alcyone
top left, Merope bottom left and Maia bottom right. The object is
surrounded in Greek mythology with some of the sisters being involved
with Zeus and Posiedon. Pleiades is located in the constellation of
Taurus and is about 400 light years distant. I plan to re-shoot
this in a wider field and attempt to get all seven sisters. Taken
on 09/24/04.
M33
This spiral galaxy also known as the Pinwheel is located in the
Constellation of Triangulum . It's about 3 million light years
distant and spans 50,000 light years. It is part of a group of
galaxies known as the Local Group. Included in this group is our
own Milky way, Andromeda and about 25 other galaxies.
Many areas of nebulosity can be seen as a red glow and some
emission nebula areas can be seen in blue. Other areas are rich
in star clusters. Image is a 200 minute LRGB taken on 09/24/04..
M74
This galaxy resides towards the constellation of Pisces and is
approximately 30 million light years away. Some consider this the
perfect spiral galaxy and a better image would show why. The
significant difference between
this image and M33 is the atmospheric conditions of the
evening. Haze, humidity and air turbulence can dramatically
affect
the clarity of even a well focused system. I will of course redo
this at a latter date.
