The Vicissitudes of Life, Photography and Weather

If vicissitude is a long word, do not worry. It means:

a change of circumstances or fortune, typically one that is unwelcome or unpleasant.

Here in California we are finally getting much-needed rain.  The drought has been more severe than when we moved here 25+ years ago. Showers and clouds are quite welcome in these parts, provided they do not block out the next great celestial event.

The next great shower is the Geminids on the night of December 13th into the morning of December 14th.  Fortunately that is a weekend, unfortunately the moon is in its last quarter so it will rise near midnight just as the shower generally becomes more intense.

How to Watch a Meteor Shower

There are many guides on what to do to SEE a meteor shower, but we can boil it down for you:

  1. Dress very warmly. A thermos of hot beverages is strongly recommended.
  2. Get in as dark a sky as possible away from sources of light pollution, streetlights, etc. Do not use a flashlight. Let your eyes dark adapt so they can see their best.
  3. Get a comfortable fully reclining chair and look STRAIGHT up.  You’ll see more meteors if you can see the entire sky. While the meteors will appear to come from the constellation Gemini they can appear anywhere in the sky.
  4. Bring a friend along and share the wonders of the heavenly fireworks with them. Besides, officially you didn’t see a meteor unless two people saw it or you got a photograph 🙂

The constellation Gemini – from which all the meteors of the shower appear to radiate rises at about 7:30 PM local time in the North East.  At that time, the Andromeda Galaxy will be almost straight above you for most people in mid-northern latitudes. By midnight, Gemini will be overhead. We recommend a Planisphere or an app if you want to identify the constellations, but to enjoy the shower you need nothing but your eyes.

Photographing a Meteor Shower

In prior articles have covered how to find a dark location and how to plan for and photograph a meteor shower.  And we even have a thorough article that explains why you probably DID NOT photograph a meteor.  We even have led expeditions to capture meteor showers in a dark location.  Unfortunately this year we have faced other vicissitudes.

Showers in Life

We could not deliver the content you requested used too many times

Download link error – hopefully resolved now.

We have weathered several storms ourselves recently, and like you find ourselves wondering where all the time went.  Most recently we were reminded how difficult it can be to maintain a website and sell digital goods. An increasing number of customers complained that the digital goods they ordered could not be downloaded.  We discovered that Google was the problem! We had been using goo.gl to create short links instead of long, sometimes multi-line links for downloading content, but Google insists – for your safety – to check the contents of each of those links.  It would have been fine had this happened once or twice, but we noticed that Google US, Google Czechoslovakia, Google Japan, and Google Brazil (and others) all separately scanned the links, sometimes multiple times.  And then your virus scanner may also have downloaded and inspected the content before it would let YOU have it…  It was a lot of wasted bandwidth and irritation. We rejiggered our software to resolve the issue. Bottom line if you recently purchased content and got a “Too Many Download Attempts” message, we think it should now work if you try again. We apologize for any inconvenience.

Also, as you may know, running a website is not for the faint of heart. For example, we are seeing another increase in attacks from Chinese Comment Spam robots as well as attackers in the countries of Georgia and Germany.

On a personal matter, Steven – the primary contributor to this website – was the sole survivor of an entire team that was laid off at his day job. Steven was fettered with sole responsibility for a vast armada of servers and networks – which all fell on their knees when a 30 second power interruption wreaked havoc. He also found that there were problems with his own home network which he has been building to be able to conduct webinars again (and to thwart robocallers) … His home network is still not reliable enough, unfortunately!

Meanwhile, we are still working hard on our 2015 schedule of events.  Please bear with us. Our next article will be about pin-point stars in landscape astrophotography.

Road Trip: Eastern Sierra, California

Do you know how to get permission” … is how it began.  And this question set in motion a two-and-a-half day trek with 16 hours (800 miles) of driving plus the usual sleepless nights.  The first night found us shivering at Mono Lake.  I knew it would be cold, but it was colder than I anticipated and my 7 layers of clothes were just barely keeping the frigidity at bay.  Unfortunately due to a low fog that crept in and the aforementioned bracing cold, we were unable to hang out until moonrise which that night was to be at 12:20 am.

Takeaway: Always be prepared for 20 degrees lower temperature than the forecast!

After sleeping in, and grabbing breakfast we took a long drive to Bishop by going through Benton and stopping at several Petroglyph sites.  There were some remarkable locations I’d never seen before along the route, including a place that looks strongly like the formations at Alabama Hills.  Unfortunately the photos I took with my Spyglass application were never saved… we’ll be talking about Spyglass in the future, so stay tuned.

The second evening we found ourselves at 7,200 feet elevation where clear skies turn a noticeable purple after sunset. But I talked Mr. Mean 🙂 into remaining until at least moonrise which on that night followed the rise of Sagittarius.

WIth Tioga pass closed, we traveled through Sonora Pass on the way out and by accident through Carson Pass on the way back.  There was precious little snow anywhere except in Carson Pass.  The area around Caples Lake was particularly nice.

Caples Lake, Ebbetts Pass, California. This is a little bay in the lake the lakes is MUCH larger.

By the way, I’ve referred to Andy as Mr. Mean only because he was insistent that I not pay for the gasoline for this long trip.  I don’t think he really has a mean bone in his body. Meanwhile, you might want to check out his antics on his blog: PhotoshopScaresMe.com

The Elusive Milky Way – How to Find It!

Last revised: May 9, 2017
Original Publish Date:  June 26, 2012

This is Part 1 of a multi-part series on finding and photographing the Milky Way.  From November through February it is impossible to spot the densest part of the Milky Way because the sun is hovering there. Read on for more information.

What IS the Milky Way?

Path of the Milky Way West-to-East

The Milky Way in Summer from Horizon to Horizon

We are located in a corner of the heavens of a galaxy we call “The Milky Way.” The Milky Way stretches all the way across the sky and some part of the Milky Way is present every night – indeed EVERY star you see in the sky is located within our Milky Way.   Most people, however, think of the Milky Way as the cloud-like stretch of stars from the constellation Scorpius (aka Scorpio) to the constellation Cygnus – particularly the part nearest to Sagittarius.  I’ll try not to be too poetic, but when you have clearly seen the Milky Way, it is hard to describe how awesome it is without breaking into song. In ideal conditions the diffuse light of the Milky Way can cast a shadow on the ground!  Unfortunately there is little chance that you will ever see that shadow because most accessible places in the world are mildly to HORRIBLY light polluted. Constellations that are found in the Milky Way include:  Perseus (off the bottom), Cassiopeia (near the bottom in the picture above-left), Lacerta, Cygnus (near the center), Aquila, Sagittarius, Ophiuchus and Scorpius (very top).  Those in the Southern Hemisphere will also find Norma, Circinus, Crux, and Carina.  There is a faint portion of the Milky Way visible in Puppis, Canis Major and the bow of Orion. Look carefully at the image above and you’ll see a bright “smudge” in the center of the bottom fourth of the image. That is one of our sister galaxies known as Andromeda. The galaxy gets its name from the constellation in which it is found.  With an unaided eye it is readily possible to spot Andromeda in a dark sky. With binoculars Andromeda is observable even in a suburban area. In the southern hemisphere two additional sister galaxies called the Large and Small Magellanic clouds are easily seen. On a dark clear night it is easy to observe the lack of stars in the broad band of wispiness that forms the Milky Way. But the dark void is not due to the absence of stars. The void is due to immense inky dust lanes that obscure the stars!

When to See the Milky Way

The sun is in the constellation Sagittarius in December so during November, December and January it is impossible to view the richest part of the Milky Way.  October and February are generally impossible, too. The optimum viewing time in the Northern Hemisphere is in the summer when the sun is on the opposite side of the sky. Unfortunately summer in the Northern Hemisphere is also when hot, stormy, cloudy weather is doing its worst and also when the nights are the shortest. Those in the Southern Hemisphere have an advantage – longer and cooler nights during winter mean the air is clearer. Using a simple tool called a planisphere it is easy to predict when and where to look for the dense part of the Milky Way. But what must also be factored in is the location and phase of the moon. The time of year and the direction of the least light pollution also frame the parameters for getting the best view of the Milky Way. Generally the dense part of the Milky Way is best viewed when it is as high as possible in the Southern sky. Facing south during April and May the pre-dawn hours are best. From June to early August the best time is near midnight, though the Milky Way will be visible almost all night. From Mid August through September the best time is soon after the sun has set and the sky has grown dark. Below is an illustration that may help you. It was created for 38 degrees North latitude, but will serve the middle of the United States, Southern Europe, Northern China, Japan, and any location at a similar latitude very closely.  The farther North you go, the lower in the southern sky the Milky Way will be.  If you live above 65 degrees north, you will never see the Milky Way core because it never rises above your local horizon. The circle in the image below indicates the star Alnasl in the constellation Sagittarius. Above Alnasl (the spout of the teapot) is the center of our Milky Way Galaxy.

Month Best Time (Local Time) Moon Phase*
  January IMPOSSIBLE
  February Difficult. Before sunrise (late February only) 3Q to New
  March Difficult. Before sunrise New to 1Q
  April 4 AM to Sunrise New to 1Q
  May 3 AM to 6 AM New to 1Q
  June 10 PM to 2 AM New
  July Sunset to Midnight 3Q to New
  August Sunset until 10 PM 3Q to New
  September Sunset until 9 PM 3Q to New
  October Difficult: Sunset (early October only) 3Q to New
  November IMPOSSIBLE
  December IMPOSSIBLE

*1Q means first quarter moon (half full). In its first quarter the moon rises around noon and sets near midnight. 2Q is a Full moon. Nearly full is called a Gibbous. It is nearly impossible to see the Milky Way when the moon is near full. 3Q is the third quarter (also half full) moon which rises near midnight and sets near noon. New means the moon rises and sets very near the sun. Includes a slender crescent phase, too.

Where to See the Milky Way

Central Nevada, Eastern Utah. Montana. In short, remote areas far from city light pollution afford the best view. But if you know what to look for and when and where to look you can spot the Milky Way from many places throughout the world. Or you can wait for a massive regional blackout. I have seen the Milky Way very clearly from the top of Mission Peak in Fremont, California – an area with over 8 million people in literally every direction. However that glimpse required that the entire Bay Area be blotted out by low, heavy fog. My perch was above the darkness blanket that the fog provided. Yosemite National Park is still mostly dark despite cities like Fresno that are doing their best to ruin the darkness. As Numerous at the Grains of Sand Anywhere along a remote area of the coast far from cities there is a chance to see the Milky Way. For example, I spotted a washed out Milky Way just 8 miles north of Santa Cruz, California.  A long exposure and some photo editing improved the view.  If you get farther away from civilization the results can be much more spectacular as you see here. Finding somewhere in the country where it is truly dark, like the Black Rock Desert in Nevada, or White Mountain in Central, Eastern California the Milky Way reaches its most inspiring awesomeness. If you live outside the United States, do not despair, you have a good chance of seeing the core of the galaxy from anywhere south of 55 degrees northern latitude. Above that latitude the core of the Milky Way will never rise above the horizon.

How do I See the Milky Way

Visor View [C_033780]I know what you’re thinking: don’t I just “look” in the right direction? The answer is no! It takes your eyes 15 to 20 minutes to see their best in the dark.  Any bright light source in the direction you look will diminish the view. Running out of a well-lit house, or jumping out of a car where you’ve spent the last 15 minute driving with the headlights on will make the Milky Way far less awesome.  Avoiding ALL light and shielding your eyes from anything you can’t avoid will help a lot.  Do you see the Milky Way in this photo from the top of Clouds Rest in Yosemite? I promise you it is there. It juts out above the Yosemite Valley near the center of the image. Here is a view from the wilderness in Yosemite.

Can You Help Me Find the Best Time Where I Live?

In short, no. Please read through the comments for many such questions and answers. It’s impossible to cover information for everywhere on earth, but our notes here cover all the general concepts. Moreover, the moon phase is different so even though the Milky Way may be glorious this year on say August 8th, next year the moon may be full and obscure your view. Also, weather conditions may affect your view, so do not neglect that variable!

How Do I Photograph The Milky Way?

Cameras are getting better all the time, and there are some nifty tricks you can use to make a compelling photograph of the Milky Way even if your camera is not the top heavyweight performer in the gear smack down.  We’ll cover cameras and techniques in installment 2 of this series!
