The Bard and the Heavens

My wife Linda and I have a number of things about which we are passionate. This blog is representative of one: astronomy. We not only enjoy exploring the sky, day and night, but we enjoy sharing it with others. Inspired by pioneering sidewalk astronomers like John Dobson, we occasionally participate in "star parties", joining other amateur astronomers in sharing views of and information about the planets, stars and celestial events with the public.

Another of our passions is William Shakespeare, a bard (storyteller). Shakespeare was one of the most famous storytellers of all time. We are active supporters of local Shakespeare companies such as Shakespeare Dallas.  We not only enjoy their productions but believe in and support their efforts to make Shakespeare accessible and relevant to everyone in the Dallas area.

For a long time, we have had a vision of bringing these two passions together. About four years ago, we started discussing this idea with Jenni Stewart, Associate Artistic Director of Shakespeare Dallas (SD). She got excited about the possibility of doing something that brings the art of Shakespeare and the science of Astronomy together in a unique way, providing a special experience for the people of the Metroplex. This fall, working with Jenni and with Matt Cooper, the observing coordinator for Texas Astronomical Society (TAS), we finally made it happen!

On Thursday, October 3rd, 2019, SD continued their fall production of Macbeth, taking it from their home base in Samuel Grand Park out to a new venue in Coppell, The Sound at Cypress Waters. That evening, a conjunction of Jupiter and the Moon took place during the twilight period before the play and continuing on into the darkness of night. Per arrangements made with Jenni, a special area was set up next to the audience seating area. Matt and another TAS member Dennis Wardell brought out their telescopes and set them up while the audience was arriving to see Macbeth. Linda and I also set up one of our telescopes. Throughout the period before the play and during intermission, we treated people attending the play to views of Jupiter, the Moon and Saturn. They learned about conjunctions, lunar phases, the geography of the Moon, the moons of Jupiter (all four were visible), the rings of Saturn and more.

Based on reactions from the audience, I'd say the event was a smashing success. So much so, we had more telescopes out at performances over the next two nights.

So, what did starring at the sky have to do with Shakespeare or, in particular, the play Macbeth? Here is the flyer we handed out to people attending the viewing and the longer version made available on the Shakespeare Dallas event page on Facebook:

This is not the end, just the beginning... Jenni is already working on an idea to do an event specifically focused on Shakespeare and astronomy, this time at the main SD location at Samuell Grand Park. Stay tuned!

Mercury Transit 2019 - The Last One in North America for Thirty Years


Unlike the last Mercury transit in 2016 (see posts here and here), I didn't get a chance to photograph this latest one (November 11, 2019) as we were traveling and it wasn't feasible to drag all my gear with me. However, I did get a chance to watch part of the transit. That was a relief since the next one visible from North America doesn't occur until 2049.

What made viewing this transit particularly special is where we were and who we met.

As we were visiting New York City, I checked online and found a public viewing event, one that happened to be on an aircraft carrier, the USS Intrepid. Retired in 1974, the Intrepid has permanently moored dockside in NYC and was opened in 1982 as the Intrepid Sea, Air & Space Museum. Among other things, they have a space shuttle on display in a dedicated hanger, the Enterprise (the one used to prove the shuttle concept). If you are ever in New York, I highly recommend checking it out!

The host for this viewing was Joseph Martinez, better known on the streets of The Big Apple as the Joe of Jupiter Joe's Sidewalk Astronomy (here on the Web and here on Facebook). Joe is an avid amateur astronomer who loves sharing information on astronomy and views of the sky with people. Joe is also a JPL/NASA Solar System Ambassador. He and some friends had two telescopes equipped with solar filters set up on the Intrepid flight deck, sharing views of the transit with museum visitors.

My wife Linda and I checked out the view from each telescope and then struck up a conversation with Joe. As Linda has worked for many years as a planetarium educator, as I am a member of the Texas Astronomical Society and as we've both been involved in numerous viewing parties including past transits, we had a lot of common interests and activities to talk about with Joe.

When the discussion touched on the 2017 total solar eclipse and then the next eclipse in 2024, Linda suggested Joe should visit us in Dallas since we are in the path of totality. It turns out he is already making plans to be in Texas for the eclipse. Coincidentally, it also turns out he knows other planetarium educators in Texas whom Linda has worked with. Small world!

Joe, thanks again for the views of this transit! Perhaps will see you for the eclipse in 2024!

BTW, for some beautiful shots of this transit, check out ones posted on Earth Sky News.

Ten Years On...

It occurred to me while working on the previous post that this year marks a decade since I started this blog. I created it in January 2009 to help celebrate the International Year of Astronomy.

I've not been consistent in adding new content but as I look back over posts from the past ten years,  I'm pretty jazzed... there have been a lot of cool things happen. Hopefully, a few people have gotten something out of the time and energy I've poured into this thing.

Here's to the next ten!

Total Solar Eclipse Revisted

Almost two years ago, I experienced my first total solar eclipse. My plans for capturing the eclipse were a bit of a bust but I was able to get to clear skies and witness totality with my own eyes which was, in a word, awesome!

One of several citizen-scientist experiments I planned to participate in was Eclipse Megamovie, a partnership between Google and Berkeley in which photographers along the path of totality would submit their photos to be stitched into a movie that would give scientists a view of changes in the solar atmosphere throughout the eclipse. Since I was not able to capture any suitable photos during totality, I didn't have anything to submit. Still, the movie was cool to see when it came out as was the promise of the scientific discoveries to which it might contribute.

This past week there have been two new solar eclipse-related events. At the end of June, the Eclipse Megamovie project released a new version of the movie. This one has the advantage of all images being synced using the star Regulus which was visible near the sun during the eclipse. They also used a false-color technique that brings out a lot of interesting detail. Check it out below.

Next, on July 2nd, there was a total solar eclipse that crossed Chile. One thing that was special about this eclipse is that the path of totality went right over the ESO La Silla Observatory on the edge of the Atacama desert. Early reports indicate observers had a very successful eclipse viewing. See video below.

Lunar Eclipse Mania!!!

While the Internet and both digital and print media made a big to-do over the recent lunar eclipse, the January 2019 Super Blood Wolf Moon, I was actually a little disappointed in this one. Yes, it was big. Yes, it was red. Yes, it was, well, a Wolf Moon (the name used for a January full Moon for centuries, according to the Farmer's Almanac). But there's a problem... it was almost straight overhead.

Why would that matter? If your primary interest is being able to see the entire eclipse, start to finish, then there's no surer bet than a night like Sunday night. A great example is the wonderful composite by a fellow Texas Astronomical Society member, Jason Ware (you can see the original post for this on Facebook here).

Jason Ware Jan 2019

Another of my favorite shots from this latest eclipse was from a Canadian astrophotographer, Alan Dyer (below and here). Similar to Jason's shot above, I like how both are a composite that show the key points in the sequence.

Alan Dyer Jan 2019

However, for me the Moon is often more interesting seeing it juxtaposed against something earthly, whether man-made or natural. Here are a few examples from past lunar eclipses I've shot.

This first shot below was taken in September 2015, the day before my wife's birthday, while we were in the Northwest visiting friends who live in Vancouver, WA. Shot just east of Portland, that's a very bald Mt Hood below the Moon (snowfall had been pretty sparse that year). The eclipse was already in progress as the Moon rose that night so it was in totality by the time it was just above the mountain. What an incredible view!

Nathan Eaton Sept 2015

Of course, sometimes a lunar eclipse occurring when the Moon is close to the horizon is not a blessing. For example, the shot below was taken of the January 2018 Super Blood Blue Moon setting over downtown Dallas. It occurred during morning twilight so the sky brightened well before the eclipse was over and before the Moon had set, making it difficult to really get the full effect of the total eclipse.

Nathan Eaton Jan 2018

On the other hand, sometimes what you see in an image is not necessarily what it looked like in person. Whether you realized it or not, I bet you have seen a widely shared, simply amazing view of the Moon above a city skyline or similarly distinctive foreground, one where the Moon just jumps out at you! Often times, this is really a combination of two great shots, one of the foreground and one of the Moon but where the Moon had been altered by enlarging it and possibly moving it to strategically position it in relation to the foreground. I think many of these are really stunning and a joy to see. What bothers me is when it isn't made crystal clear that the photographer has taken poetic license, that it isn't a realistic portrayal of the Moon. Thanks to the Moon Illusion, we are used to to the idea that the Moon looks larger close to the horizon so it is not surprising that many people assume a shot where the Moon looks larger than normal is real. 

A variation of this is composites similar to the ones above but where they are over a foreground subject. I am a big fan of these but, again, when the Moon is shown "larger than life" relative to the foreground, I think the photographer needs to call out the exaggeration. A great example of this done well, both the photograph and the photographer being upfront about what changed, is this shot by Jason Weingart that was highlighted in PetaPixel

Jason Weingart Jan 2019

As another example of why it's important to be clear about when a shot has been materially changed, consider this post of a "larger than life" shot of the moon by Beau Rolfe on Facebook. In Beau's very cool shots, taken of the December 2018 full Moon, the lunar orb really is this big, but it's because it was shot with a really long lens (600mm), not because he edited the image in software to make the Moon look larger or shot the Moon with a longer lens than the foreground was shot with. Regardless, his shots still raised questions of "where can I go to see it that large?" and "was this Photoshopped?" (questions friends of mine brought these shots to my attention to ask about).





When you have a lunar eclipse like this month where the Moon is high in the sky, the focus (at least for photography) turns more to the Moon itself rather than the Moon and a foreground landscape. Here are examples of that, one from April 2014 when we were at the Perot museum into the middle of the night for an eclipse party and also a similar one at height of the latest eclipse, taken Sunday night from our backyard. Both were shot through our 10" Dobsonian telescope, captured with camera on my phone pointed through the eyepiece. Not ideal (see the lens flare in first one and the "field of view" in second) but I think they are still interesting shots.

As fun as it is to see all the different ways in which people shoot an eclipse, I also like the other ways in which people celebrate the eclipse. For example, I didn't make it there but one of our favorite watering holes, The Flying Saucer, had a unique way of celebrating, offering "Moon related" adult beverages.



One of the other fascinating aspects of this eclipse is the historic first sighting of a meteor strike during the eclipse. A key contributing factor to discovery of this event was that scientists were actually looking for it. It would have been pretty incredible to have been watching through my telescope just as the strike occurred!



To close, I'm including a couple of shots I took from the backyard Sunday night. First, a shot taken with my Nikon D750 using the longest lens I had handy, a 120mm Nikkor (actually, the D750 kit lens, a 24-120mm zoom). Image is cropped from an HDR stack of three bracketed shots.

Finally, here is is a shot of the evening with us huddled around the fire pit trying to stay warm while watching the eclipse with our 8 month old Weimaraner, Luna. Not only is her given name take from the Moon, but her AKC registered name, suggested by our granddaughter Kai, is based on such an event: Runner's Lunar Eclipse. Seemed fitting to have her out with us while we were watching such a beautiful sight. I hope you were able to catch a glimpse of it, too!
