Sky, Eye, and Camera: Special Opportunities for October 2014

Note: This is a new feature about events each month that are not only fun to observe with eye and binoculars, but are particularly suitable for capture as photographs –  especially photographs that convey a sense of being there and are taken with ordinary cameras.   While taking night sky photographs used to be more demanding, modern digital cameras don’t have to go to bed at night – they’re a great addition to your night sky enjoyment. Greg Stone

September 2013 - Full Moon rises shortly after Sunset with the Earth's shadow as backdrop, topped by the rosy "Belt of Venus." This shot was easy because the Moon is so bright.  But on October 8, 2014 I expect a similar situation in the morning western sky just before Sunrise. However, in that case the Moon won't simply be in line with the Earth's shadow - it will be in it, fully eclipsed. Under such circumstances will be able to see it?

Photographing October’s Lunar Eclipse

The moon makes all sorts of news this month, but for U.S. East Coast dwellers such as me the big photo opportunity will be the total Lunar eclipse on the morning of October 8, 2014.

In addition, much of North America will see a partial solar eclipse as the Moon’s shadow falls on the Earth October 23. On October 17 and 18 the Moon plays tag with brilliant Jupiter in the morning sky. Then in the evening sky on October 27 and 28 a waxing crescent will dance above the Teapot right in the Milky Way and Mars will join it. Whew! Real lunacy this month! 😉

But I’m keeping my fingers crossed about the weather for the total lunar eclipse. This is one of four in a two-year period with others due next spring and fall. The first in this series –  last spring – was clouded out for me and I at first thought this one would be uninteresting, coming as it does, right near sunrise for my location. But that’s actually going to make it all the more interesting – especially from a photographic perspective! Here’s why.

Totality actually starts at 6:25 am EDT, 23 minutes before sunrise. Now I figure 5-10 minutes after totality begins the Earth’s shadow and the Belt of Venus should be visible in the west as they are about 15 minutes before every sunrise. But this time the Moon itself will be in that shadow.

How cool that will be! But, I’m holding my excitement because it could also be all but invisible!

It would be cool because during the typical total eclipse the Moon is in a dark sky and we can’t see the Earth’s shadow – we just know it must be there because the Moon is getting darker on one side as it moves into  it.  But this time we will have a totally eclipsed Moon sitting right inside the Earth’s shadow which we will see – weather permitting – the entire length of the western horizon.

Now I have no doubt that we will see the Earth shadow – we see it every clear morning – but will we even be able to see the Moon at that point? When totality starts the Moon will be only 4 degrees above the horizon. It sets – locally – about five minutes after sunrise. We can, of course, see even a crescent moon in broad daylight – but this is an eclipsed Moon.

So will it be visible at all and how visible? Even during the partial phases I expect it to be a little hard to pick up in a brightening sky. The partial eclipse begins at 05:15 am EDT. Astronomical Twilight – the first detectable lightening of the sky – starts a couple minutes later.

So during the partial phases we’ll have a moon that’s getting darker and darker and a sky that’s getting progressively lighter. Not much contrast. Civil Twilight begins at 06:21 for me with the moon is a tad less than five degrees above the horizon and close to totally eclipsed.

But now the question becomes how clear is the western horizon? The slightest bit of cloudiness will show up and obscure the moon when it’s at that altitude.

So the bottom line is this: I have no doubt that I will see the early stages of a partial eclipse. I simply don’t know at what point – even given perfect weather – it will start to become difficult to see and lose it’s appeal as two things work against visibility – the lightening sky and the Moon drawing closer to the horizon.

This, of course, will make it a challenging photographic target – but then remember, the camera can see things that are a bit fainter than what our naked eye sees – even with an exposure of just a second or two. Tripod needed, of course, and remote shutter release handy. But wait – we will be so close to dawn we can’t use a real slow shutter speed or it will wash everything else out. And that’s where I’m thankful for digital cameras because they’ll let us take test shots and check the results, immediately, over and over!

It’s probably a pipe dream,  but I would really like to see – and photograph – a beautiful shadow of the Earth topped by a deep red Belt of Venus with a barely detectable full Moon sitting on the horizon in the middle of the Earth’s shadow. Last year I got the full moon rising with the Earth’s shadow as a backdrop – that was neat, but of course the Moon wasn’t actually in the shadow at that point and it was at its  brightest.

Technically possible, I guess – so I’m skeptical, but please – surprise me!

In any event, here’s the complete relevant time table. The  lunar eclipse times are constant for any location, though of course you will have to convert them form EDT if you’re in a different zone. Sunrise and twilight times are strictly local. They apply to my location in southeastern Massachusetts and should be checked locally. To find them I use the service provided  by the Naval Observatory and found here.

October’s Partial Solar Eclipse

From a photographic stand point I find a partial solar eclipse far, far, far less exciting than a total solar eclipse and more dangerous. You simply need to know that you shouldn’t be looking at the sun, even partially eclipsed, without special protection for you and your camera.

But if you’re in a section of North America where the partial eclipse will be good, I suggest you check out this site to find exact times for your locality – http://www.timeanddate.com/eclipse/solar/2014-october-23 

 – and then go here for observing and photographing information.


Because the Moon’s shadow seeps across the Earth during a solar eclipse, the time they occur depends on your location. With the lunar eclipse they happen at the same Universal Time everywhere as the Moon moves into the Earth’s shadow – but, of course that time has to be adjusted for time zones.

Other Special Night Sky Photo Ops in October

My goal, as always, is to include that most beautiful – and interesting – of planets, Earth, in any of my astronomical photography. To that end the idea is to look at when planets and the Moon approach closely and plan in advance what you wish to include in your Earth-sky photographs.

You don’t need a special event – or even the Moon – for this sort of thing, of course. I was photographing Saturn, Mars, and Antares with a crescent Moon low in the west over a seacoast last month. I was happy with this result.

But I was happier when I turned around and caught the outlines of some folks sitting on a nearby large rock, as well as the glow of distance city lights to the north and the rising stars in the general area of Perseus and Triangulum. (Both these images need to be clicked on and displayed  large to see details.)

So here are the situations I would anticipate as offering some special opportunities this month.

Jupiter is quite high in the Eastern morning sky and very bright, so just about any time this month it offers a good twilight opportunity with the stars of nearby Leo. With it this high, however, you’ll probably want to be closer to foreground objects – trees, buildings, boats – whatever  – to include them.

A couple hours before sunrise you’ll find Jupiter roughly 45 degrees (4-5 fists) in the eastsoutheast and unmistakeable as the brightest “star” in the sky.

On the mornings of October 17 and 18 it will be joined by a waning crescent Moon less than 10 degrees – one fist – away – a nice combination. To take advantage of this you want to scout out locations that would offer a nice, twilight scene to the southeast.

The evening sky will offer a simlar situation, but with a waxing crescent Moon and the center of our Milky Way as background. Mars will be in the vicinity, but the distinctive “Teapot”  asterism which highlights Sagittarius will make it especially interesting. Will the Moon totally drown out the Milky Way? Certainly it will impact some of it, but this will be an interesting night sky challenge

Starting on the evening of October 26 a waxing crescent about three days old will form a rough triangle with Saturn and Antares low in the south-southwest. Antares and Saturn may be too low to see depending on how clear your horizon is.  The Moon you won’t miss.

In the next two days the Moon climbs higher and moves in the general direction of Mars, the Teapot, and the Milky Way. I think this provides an interesting combination through the 28th, but with each successive day the moon gets brighter and brighter, and thus will drown out more and more of the Milky Way in it’s area.  So I think the best opportunity will be on the 26th – but you can only be sure by getting out and seeing – and snapping.
