We've had a pretty good run of cool clear nights as the moon is approaching 1st quarter.  It was a perfect time to capture some close-ups of the incredibly varied Moonscapes.  A close inspection of the shadows cast into the crater bottoms shows just how jagged the peaks can be rimming the craters.  The largest, very round and flat-bottomed crater in the bottom picture is the best example.  This crater, named after Archimedes, is about 50 miles in diameter and 1.3 miles deep.  For reference, the Grand Canyon is about 1 mile deep, on average.

Sun's Surface and Prominence

Today was my first real attempt to image the Sun's surface and a pretty large solar prominence.  A huge thank you goes out to Marty for posting a really helpful YouTube tutorial on his Wise Imaging channel.  I still have a ton to learn and practice at this form of imaging, but overall I think it was a decent first attempt.  

The prominence is made up of plasma which is a hot blend of hydrogen and helium that's electrically charged.  There's magnetic fields involved and when they become unstable they erupt outward to release the plasma.

Early Phase Moon

The Moon is always a great target and it's rare when I'm able to catch an early phase due to trees on my horizon.  But a couple nights ago, things lined up just right and the sky was perfectly clear.  It's going to be fascinating watching NASA go back to the moon in 2024 with crewed missions.

Venus

Over 400 years ago, Galileo Galilei made the first recorded observations of the phases of Venus as we and it orbited the sun.  These observations were critical to support the Copernican system (Sun-centered) while ruling out the older Ptolemaic system (Earth-centered).  Venus is easily visible with the naked eye as it's the brightest object in the night sky, except for the moon.  Since it orbits closer to the sun than Earth, we always see it relatively close to the sun; just after sunset or around sunrise.  Through a telescope, it's phases are clearly visible, but all we are seeing is the very thick atmosphere reflecting light.  The atmosphere, made mostly of carbon dioxide, is so thick it's the hottest planet in our solar system where temperatures can climb to 880F.  Hot enough to melt lead.  Given its extreme environment, it's a tough planet to explore.  More than 20 missions have been directed to Venus, but only a few (from the Soviet Union) have ever made a landing.  The missions were typically very short-lived (minutes to days) before the craft were crushed and melted by the very atmosphere they were sent to study.

Messier 97 and 108

Messier 97 (Owl Nebula) and 108 (Surfboard Galaxy) are both located near the scoop of the big dipper in the northern sky.  While they appear to be of similar size, it's merely an optical trick.  The diameter of the Owl is about 3 light years while the Surfboard galaxy from end-to-end is 100,000 light years, or over 30,000 time larger.  The similar apparent size comes from their distances.  The Owl is only about 4,000 light years away and the Surfboard's light has been traveling to us over the last 46 million years.

The Owl is a planetary nebula with a triple shell structure of gas.  The two dark spots (eyes of the Owl) are caused by bipolar activity in the central shell of gas.  We are seeing the Surfboard galaxy from the side, but astronomers believe it's a spiral galaxy with some areas of young star formation.

Messier 42 - Orion Nebula Update

I was able to get out again last week to again target the Orion Nebula.  My previous image had just 1 hour 24 minutes of total exposure time.  The one above included that with a second night of imaging for a total of 2 hours 30 minutes.  The net difference was being able to bring out a lot more detail.

Messier 42 - Orion Nebula

The best winter sight, by far, is the Orion Nebula (Messier 42).  I've photographed this one a few times previously, but this was my first attempt with my wide-field telescope.  While it would have been nice to have more time on it, it turned out fairly well.  I shot 40 frames at 3 minutes per frame, but it must have been a busy night up there because 10 of the frames had airplane or satellite tracks through them and had to be discarded.  The net time was 1 hour 24 minutes.  I'd love to come back when the weather clears to try and double the total exposure.

Moon 2020

First astrophotos of the year were, of course, the moon!  I really need to make an effort to shoot from some different locations.  My sky availability at home basically gives me right around the first quarter to full moon which is great, but I miss out on a lot of interesting features that are only captured during earlier phases.  Until I make that effort, these will have to do!

Messier 16 (War) Eagle Nebula and the Coat Hanger

Messier 16 (War) Eagle Nebula

Coat Hanger Asterism

Friday night brought clear skies and (reasonably) dry air and it was the perfect time to get out for some deep sky imaging.  The first target was Messier 16, otherwise known as the Eagle Nebula.  I added the (War) in honor of the first victory of the year for the Auburn Tigers.  I've imaged M16 a few times and this one may be the best one yet.  The "elephant trunks" in the middle were imaged by the Hubble Space Telescope and became one of the most famous images of all time and are known as the Pillars of Creation, an active star forming area.

The second image is known as the Coat Hanger asterism for obvious reasons.  I wasn't able to fit all the stars in the image; there's a few more off to the right.  Still, it's a striking collection known especially for it's shape and the sharp contrasting colors between the starts.

Jupiter & Saturn

A week of beautiful weather encouraged me to get back out and image some planets.  Saturn is busy chasing Jupiter across the sky at sundown and neither disappointed on the two clear nights we had this week.  You might notice the small spheres at about 7 o'clock on Jupiter.  That's the moon Ganymede just finishing it's transit of the surface.

Weather & Nightscapes

 

And so begins my new interest in photographing weather and nightscapes.  We had a week of gorgeous skies in Wisconsin at Castle Rock Lake followed by a beautiful night here in the south.  This kind of photography poses its own unique challenges, but sure is fun!

More Moon

Just over a week ago we had a remarkably clear and cool night, or what passes for clear and cool here in the South.  It had been a while since I'd been out to image anything and the Moon, as always, put on a fantastic show.

Super Blood Wolf Moon

Eclipse Update:  I had time to go through the rest of the images and put together this short video.  The images are about 10 minutes apart until the moon is fully eclipsed.

We had a perfect night to watch the Super Blood Wolf Moon last evening.  It was eerie watching the shadow creep slowly across the moon's surface getting darker and redder with each passing moment.  We shot many images, that I'll process and post later, but this is the fully eclipsed moon at around 10:45 PM (CST).  Special thanks to Allison for helping record data throughout the duration of the eclipse.

California Nebula - NGC 1499

I first visited this celestial "geographic" wonder back in 2015 and was thrilled to come back a few nights ago when the skies finally cleared and we had a deliciously cold night.  This nebula is absolutely massive.  If we could see it with the naked eye, it would span about 5 moon-widths from tip to tail and about 2 moon-widths across.  However, since it is an emission nebula (think gas cloud lit by a nearby star) the light is very diffused and difficult to observe even through a telescope.  This one takes a lot of patience and faith that you're on target.  Total exposure time for this image was 2 hours.
