IC 443 - The Jellyfish Nebula
This nebula is most probably what is left of a supernova that
occurred about 30,000 to 50,000 years ago. At its center is a
neutron star that was formed when the stellar core collapsed.
The Jellyfish Nebula is in the constellation Gemini (The Twins),
and is about 5,000 light-years from Earth

The Horsehead and Flame Nebulae (Barnard 33 and NGC 2024)
This wide-field view contains both the Horsehead and Flame
Nebulae. It shows a very small portion of the great Orion
Molecular Cloud complex, which stretches from above Orion's
head (Betelgeuse) to below his feet (Rigel). It was imaged
in the HSO palette. They both lie about 1375 light-years away.
The Horsehead is a dark nebula while the Flame nebula is an
emission nebula

Wide-field view of the region around Deneb
Deneb is a very bright star in the constellation Cygnus -
The Swan, and represents its tail. Another notable star in
Cygnus is Alberio, a colorful double star system that is the
head of the swan. Cygnus is also sometimes referred to as the
Northern Cross. It is also part of an asterism known as the
Summer Triangle, which is made up of Deneb, Altair and Vega.
Its mass is about 20-25 solar masses which means that it will
end up as a supernova. It is about 2600 light-years away

LDN 1235 - The Shark Nebula
The Shark Nebula resides in the constellation of Cepheus. Cepheus
was the king of Aethiopia. He was married to Cassiopeia and was
the father of Andromeda. This nebula is classified as both a
dark nebula as well as a reflection nebula. There are two
reflection nebulae - one just behind its head and the other at
the base of its neck. Dark nebulae are very, very faint and can
only be seen in long exposure images

IC 2177 - The Seagull Nebula
This nebula lies right on the border of the constellation Canis
Major (the Big Dog) and Monoceros (the Unicorn). It is an emission
nebula. I processed this image in the HSO palette (Hydrogen alpha
assigned to the red channel, sulphur to the green channel and
oxygen to the blue channel. See the image to the right for
another version of the same object
|
IC 2177 - The Seagull Nebula
Here is another version of the Seagull Nebula. This one was
processed in the OHS palette (Oxygen assigned to the red channel,
Hydrogen alpha to the green channel and sulphur to the blue channel).
There are 24 different possible combinations to choose from. Most of
which come out in some really bizarre colors. The fun part for me
is that different details emerge with every color combination
|
NGC 2626
NGC 2626 is in the constellation Vela. Vela refers to the sail
of Jason's ship, the Argo Navis, that Jason and the Argonauts
sailed in to retrieve the Golden Fleece. There is certainly a
lot going on in this nebula, which is a reflection, emission
and absorption nebula. It has a pulsar in its midst that is
the brightest celestial source of gamma rays. It lies about 3300
light-years away

CG4 - God's Hand

RCW 32
Just about 3000 light-years from us, in the constellation Vela is
this interesting nebula. It is an emission nebula that is part
of a larger HII region
|
RCW 6 (Sh2-301)
Out in Canis Major (the Big Dog - one of two that were Orion's
hunting dogs), is RCW 6. It is a Hydrogen II region that is
about 19,000 light-years away from us
|
NGC 2264
This nebula is in the constellation Monoceros. It lies about
2700 light-years away from us. NGC 2264 actually refers to two
objects: The Cone Nebula and the Christmas Tree Nebula. Also
within this huge reflection nebula are the Fox Fur and Snowflake
Nebulae. This is a re-do of the same image on the Nebulae 3 page. I
did a real-time processing of this object as a presentation for our
local astronomy club in April 2024. I processed it at least once
a day for a month in order to recreate the first version. Never
could duplicate that first effort, but this one turned out just
as nice

Messier 16 - The Eagle Nebula (Pillars of Creation)
The Eagle Nebula is part of a huge diffuse emission nebula
located in the constellation Serpens (The Snake). It was made
famous with an image by the Hubble Space Telescope which dubbed
it the Pillars of Creation. It contains several regions of
star-forming gas and dust. This version is done in the Hubble
Palette (SHO). Thus the strange colors

RCW 61 - (Head of the Running Chicken Nebula)
Down in the southern constellation of Centaurus (The Centaur),
lies an absolutely huge nebula called the Running Chicken Nebula,
officially named the Lambda Centauri Nebula. It is roughly 7,300
light-years away from us. This portion of the nebula is the head
of the Running Chicken
|
RCW 52
This nebula is in the Carina Nebula. Carina is the Latin word
for keel of a ship. RCW 52 lies about 5200 light-years away and
is about 70 light-years in diameter
|
IC 2169
This is a reflection nebula in Monoceros, the Unicorn
|
Messier 8 - The Rosette Nebula
The Rosette Nebula is a HII region in Monoceros (the Unicorn)
and lies about 5200 light-years away. It is 65 light-years in
diameter which is about half the diameter of our own Milky Way
galaxy. The stars in the center are an open cluster (NGC 2237)
which is made up of 36 new stars. If you zoom deep into this
image and scroll through it you'll find at least an additional
45 galaxies. This image was processed in the Hubble Palette OHS

Caldwell 49 - The Rosette Nebula
This is another version of the Rosette Nebula that was processed
using the Hubble Palette SHO
|
The Dark Doodad Nebula
This one used a larger telescope which gives us a more zoomed-in
view. This dark nebula is commonly known as the Doodad Nebula.
It's a long, cold molecular cloud in the constellation Musca
(The Fly). This one almost looks like a shark standing on its
tail
|
Messier 24
Messier 24 is also known as the Small Sagittarius Star Cloud.
It is officially a star field, but there are several other
objects that surround the central star field. The object is
about 600 light-years wide. There are two distinct dark
nebulae

Sh2-157 - The Lobster Claw Nebula
This is an emission nebula in the constellation Cassiopeia. It lies
about 11,000 light-years away from us. The orange-ish area in the
center is predominantly Ha. The rest of the nebula contains various
areas of OIII and a little SII
|
Vela XYZ
Vela XYZ is a supernova remnant located in the southern
constellation of Vela. It's the expanding sphere of gas left
over from the death throes of a star. It is believed to have
exploded around 11,000 years ago, and at 900 light-years away,
it is the closest SNR known to us. This image was processed
with the HSO palette
|
RCW 40
Here is another version of Vela. This one processed with the
OHS palette. I think I like this one better than the preceding
one. I did two versions to show that by assigning the different
filters to the color channels in various combinations, different
structural details can be seen. I couldn't find the info again,
but last time I checked, I remember that the HST carries at least
52 different filters
