Moon

Waxing Gibbous

Copernicus Crater with Montes Apenninus

Tycho and Clavius Craters

I was able to get out for a short time on the evening of December 12 to do some moon shots.  The top photo was un-magnified, except that provided by the telescope itself.  The bottom two photos were taken through a 2x Barlow lens nested into another Barlow 2x lens for 4x magnification.  Tracking at this level becomes much more important and I had a lot of images I just couldn't use because I hadn't switch the mount over to Lunar tracking from sidereal.  I look forward to making another attempt soon!

Messier 74

As you can see, M74 is a classic whirlpool galaxy and is known to be the second-most difficult Messier object to see through a telescope.  The faintness in the photo above, despite nearly an hour of exposure time, is a testament to the difficulty.

M42 and 43

I had so much fun working on the Orion Nebula the other night, I decided to go back with things better positioned so I could get a much longer exposure time.  In doing so, I was able to also capture M43, the nebulous region at the top of the photo.  Though now considered to be part of the same nebulous cloud, they were originally discovered and cataloged as separate objects.  The added exposure time also brought forward so many details in the Orion Nebula.  This is surely a sight to visit and revisit many times over!

NGC 7331

This spiral galaxy is often referred to our Milky-Way's twin.  It's about 50 million light years away and is one of the brighter galaxies not included in the Messier catalog.  I'm looking forward to going back to shoot this galaxy again.  There's a lot more detail to bring out over longer exposure times.  This happened to be a target of opportunity while waiting for the Orion Nebula to rise.

Messier 2

Messier 2 was first observed in 1746 by a French astronomer, Maraldi, while comet hunting with Cassini.  Messier rediscovered it in 1760 but at first thought it was a nebula without any stars.  This star cluster is 37,500 light years from earth and is one of the larger clusters at 175 light years in diameter.  We are looking at a grouping of approximately 150,000 stars that date back 13 billion years.  These kind of numbers are just hard to comprehend!

Jupiter

Jupiter is the 5th planet from the sun and is an absolute monster!  Classified as a gas giant, it is comprised mostly of hydrogen.  Galileo famously studied this planet and observed the motion of the moons to confirm that we were decidedly NOT the center of the universe.  The stripes that you see in the picture are storm clouds.

M42 - Orion Nebula

The Orion Nebula is one of my all time favorites.  It's one of those sights that is rewarding to visit time and again.  This was my first serious attempt at photographing this stellar nursery.  The center of the nebula is actively forming stars and not too distant so we can see plenty of detail.  I was only able to get 8.5 minutes of exposure time before it passed behind the house, so I can't wait to make another attempt.  There is a lot more there to see!

M76

This was a tough image to get.  Clouds were off to the west as I set up and quickly overtook the area I was trying to photograph.  I ended up with just 15 minutes of exposure time.  This is one object I'd like to go back and get again.  It's known as the Little Dumbbell Nebula.  A quick look at Messier 27 (Dumbbell Nebula) and it's obvious how this got its name.

Nearly Full Moon

We had a beautiful night here last evening and I was able to have some fun with my new Barlow lens on the telescope.  It gave me twice the magnification and some really nice resolution.  It will be fun to try it on some other celestial targets!  The above images feature a few different post-processing techniques in Photoshop to give them a slightly different look.  The third one is just cropped so it shows a much tighter view.

M52 and NGC 869

Messier 52

The Messier catalog is full of star clusters and M52 is a good example.  It was a chance discovery by Messier in September of 1774 when he was busy chasing down a comet.  One of the curiosities of this particular cluster is that astronomers only have a very general idea of its distance and age.  They estimate between 3,000 and 7,000 light years away and between 25 million and 165 million years old.  For a typically precise science, these are incredibly imprecise ranges.  Nice to know the professionals don't know everything!

NGC 869 - Double Cluster in Perseus

This is my first astrophoto outside of the Messier list.  That, in itself, isn't anything special.  It's just such a beautiful sight, I couldn't pass it up on a gorgeously clear night.  This double cluster is an amazing sight through the eyepiece of most any telescope, and becomes even more beautiful under long exposure photography.  These cluster of starts are about 7,500 light years away and are relatively young at 12.8 million years.  There are more than 300 blue-white super-giant stars in each of the clusters.  I am also struck by the orange colored stars in these photos that provide such a nice contrast.  This cluster is featured in Greek mythology as it represents the jeweled handle of Perseus' sword which happens to be the sword that beheaded Medusa when Perseus was challenged by the gods to slay one of the Gorgons.

Messier 33 - Triangulum Galaxy

Messier 33 is known as the Triangulum galaxy.  It's one of the nearest galaxies to us, which is why it appears so large and yields so much detail.  It is about 60,000 light years across and astronomers have even been able to measure that it is rotating clockwise with one complete rotation every 200 million years.  If you look closely, you may see some faint blue patches that are young star forming areas.  This has become one of my favorites!

M45 - Pleiades

This beautiful cluster of stars is an easy object to pick out of the night sky as the summer turns to fall and into winter.  At this time of year, it hovers in the eastern sky after nightfall.  With the naked eye, it looks a bit like a question mark and is sometimes called the Seven Sisters.  Through a telescope, you can begin to see some faint nebulosity around some of the stars.  

The Pleiades have been well known since prehistoric times and figures into many cultures' mythology.  It shows up around 2500 BC in Mesopotamian mythology and Homer mentions it in the Odyssey.  It's also described in the Bible three times.  The passage from Revelations 1:16 is striking as it describes the second coming of the Messiah:

"And he had in his right hand seven stars:  and out of his mouth went a sharp two edged sword: and his countenance was as the sun shineth in his strength."

I found this passage from Alfred Lord Tennyson's poem Locksley Hall a beautiful description:

"Many an night I saw the Pleiades, rising thro' the mellow shade, Glitter like a swarm of fireflies tangled in a silver braid."

Messiers 31, 32 and 110

The main event in this photo is the gorgeous Andromeda Galaxy (M31).  There are observations of this galaxy dated to 905 AD by Persian Astronomers.  In a dark sky, it is a naked-eye object, though not with this kind of detail.  It spans a whopping 160,000 light years across and contains an estimated 700,000,000,000 solar masses.  It's hard to even comprehend the number of stars and worlds we are looking at in this one picture.  Complete humbling.  It is the closest galaxy to our own Milky way and it was Edwin Hubble who first figured out a reasonably accurate distance and that it wasn't part of the Milky Way.

The other two objects in the photo are M32 (below) and M110 (above).  M32 and M110 are physical companions of Andromeda; locked in a gravity-driven cosmic dance.  Compared directly to Andromeda, they may not look like much, but both are galaxies in their own right.

Southern Skies

Sydney Observatory

Night Shot of Scorpius at Sydney Observatory

Australia's Oldest Working Telescope

While traveling in Australia, we had the great opportunity to visit the Sydney Observatory.  It's in the heart of Sydney, overlooking Sydney Harbor.  A gorgeous site for an observatory, except for all the sky glow.  Despite that, we had a great time, learned a lot about the southern sky, were privileged to gaze through Australia's oldest operational telescope and even try a night shot of Scorpius outside the observatory.  All around, a fantastic time!

More 1st Quarter Moon

I took some time tonight to process the rest of the images taken on Saturday.  The Registax program does a great job of stacking images, but I am so tempted to go for a higher resolution camera!  I get a little disappointed with how few pixels I have to work with!

1st Quarter Moon

We had a gorgeously clear night here.  After watching the first half of the Auburn/Mississippi State football game, I decided to head out and try for some moon shots while listening to the second half on the radio (Auburn won with a decisive drive at the end of the game!!!).  For the first time, I tried using my NexImage camera with the Orion 8" scope on the Celestron VX mount.  The results were better than I could have expected.  Each shot above is approximately 1000 frames stacked and aligned using the Registax 6 software.

Messier 16

Messier 16 is often referred to as the Eagle Nebula.  One look at the photo above and you can see how this imagery would come to mind with the head facing downward and the tail highlighted by a relatively tight grouping of stars.  Technically speaking, M16 is the dense grouping of stars in the tail of the eagle.  It was first discovered in 1745, but the telescopes of the time were not able to see the nebulous cloud we now call the eagle.

To me, the most beautiful features of the eagle are the three pillars in the middle of the eagle's body.  These are sometimes called the "elephant" trunks and are home to active star formation.  Each trunk is an astounding 6 trillion miles long.

Messier 27

Messier 27 is also known as the Dumbbell Nebula.  It was the first discovery of a planetary nebula and was identified by Charles Messier in 1764, though William Herschel was the first to see the curiously stunning dumbbell shape.  My favorite description was by Admiral Smyth who said, "magnificent and singular object, it is one of those splendid enigmas which are proposed by God."  

This particular nebula is one of the most-studied planetary nebulae. Like all planetary nebulae, it is the remnant of a dying star.  What we are seeing is shell of ionized gas given off late in its life.  It is truly an awesome sight to behold!

Messier 29 and Perseid Meteor Shower

While waiting for the Perseid meteor shower to kick into high gear, we decided to take advantage of the miraculously clear skies to shoot Messier 29.  M29 was discovered by Charles Messier on July 29th, 1764.  The five brightest stars of M29 are blue super giants.  Some observers say that M29 looks like a smaller version of the Pleides.  One of the amazing things about looking at this cluster is the star field it sits within.  There are something like 600 individual stars in this photo, which makes it kind of hard to make out M29 in the middle, but it is there!

The Perseid meteor shower is an annual celestial event.  It is regular in its timing and has a decent viewing window spread over a few nights.  It's named after the constellation Perseus since many of the meteors seem to originate here, but the meteors actually come from the comet Swift-Tuttle.  Each year, we pass through the debris cloud of this comet and are treated with a light show.  The kids each invited over a friend and we had a small star party. Everyone got to see a few meteors, but we failed to catch any photographically.  We made it to midnight before tiredness, incredible humidity and bugs drove us into the tents.  The incredible humidity drove everyone inside soon after that!

Messier 57

The Ring Nebula in the constellation Lyra is the second planetary nebula ever found.  Planetary nebulae are the remnants of a dying star; the gassy shell of what it once was.  It was discovered in 1779 by Antoine De Darquir.  Although it was observed and discovered in the late 1700's, it was not until the 19th century observer William Huggins observed M57 spectroscopically that it became known as a ring of gas.  Today M57 is described as an ellipisoidally-shaped nebula, which you can clearly see, if you zoom in on the image above.  It has an inner and outer halo made up of luminous gases. These halos surround a very hot and compact central star which is the remaining core of a former red giant.  You can make this star out as well, if you zoom in.  It is believed that M57 is about 2,300 light years from Earth.

Any way you slice it, if you come upon the Ring Nebula in your eyepiece, you know you are seeing something very special.  It is hauntingly beautiful and unique.  For us it is a glimpse of the heavens and if they were that amazing 2,300 years ago, we can only imagine...
