Photograph the Total Lunar Eclipse

|Tutorials|6 Comments

Are you hoping to capture a photo of the total lunar eclipse on January 20, 2019? If so, you are not alone. Amateur photographers and astrophotography enthusiasts around the world will do their best to take a pictures of the lunar eclipse in January using a wide variety of camera equipment.

These days, every full moon and lunar eclipse has some sort of epic name attached to it, and the total lunar eclipse in January 2019 is no different. The media has nicknamed this astronomical event the Super Blood Wolf Moon 2019. That’s right, don’t forget to add the “Super”. 

Catchy names aside, a total eclipse of the moon is a truly breath-taking astronomical event that anyone can appreciate. Over the years, I have photographed a number of total lunar eclipses, and I plan to do so again on January 20, 2019. There are many ways to photograph the total lunar eclipse this January, but for the best results I recommend using a DSLR camera and a small refractor telescope on a tracking mount. 

lunar eclipse photography methods

The total lunar eclipse on January 20-21, 2019 is the only total eclipse of the moon in 2019 around the world, with a partial lunar eclipse happening on July 16 in isolated parts of the world. 

To capture a detailed portrait of the moon like the image above, a long focal length and a tracking equatorial mount are required. However, it is also possible to produce a comparable close-up image using a digital camera or smartphone through the eyepiece of a non-tracking telescope using the eyepiece projection method.

In this post, I’ll share some tips for photographing this celestial event using both basic and advanced astrophotography equipment. 

What is a Lunar Eclipse?

Do you understand why a lunar eclipse happens? There are two types of lunar eclipses: partial and total. I am happy to say that the event on January 20-21 is the extra exciting one.

As you know, the Earth orbits the sun, and the moon orbits the Earth. During a total lunar eclipse, the Earth is sitting directly between the sun and the moon. Although the moon is being covered in Earths shadow, some sunlight still reaches the moon. 

When the moon enters the central umbra shadow of the Earth, it turns red and dim. This distinctive “blood” color is due to the fact that the sunlight is passing through Earth’s atmosphere to light up the disk of the moon.

Unlike a solar eclipse, observing a total lunar eclipse is completely safe to do with the naked eye. This natural phenomenon can be enjoyed without the aid of any optical instruments, although binoculars can really help to get an up-close view of the action.

Where and When will it Happen?

The total lunar eclipse will take place on January 20-21, 2019, with the total phase visible from North and South America. From my vantage point in Ontario, Canada, the maximum eclipse will occur at 12:15am on January 21. To find out when the total lunar eclipse will take place from your location, you can check out this eclipse map on Timeanddate.com.

There are 7 stages of a total lunar eclipse, and many amateur photographers like to capture the event in each stage. This can later be made into a composite photo showing the transition of the moon as Earth’s shadow covers it. A time lapse video is another excellent way to capture each stage of the eclipse.January 2019

The maximum eclipse stage is when most photographers want a great shot. This is when the the moon turns “blood” red and the surrounding night sky becomes much darker from our point of view on Earth. It is an unforgettable experience for those lucky enough to witness this moment.

Stages of the total lunar eclipse:

  • Penumbral Eclipse begins
  • Partial Eclipse begins
  • Full Eclipse begins
  • Maximum Eclipse
  • Full Eclipse ends
  • Partial Eclipse ends
  • Penumbral Eclipse ends

An interesting thing happens when the moon is completely eclipsed by the shadow of Earth. Not only does the moon turn to an eerie reddish hue, but the stars and constellations surrounding the moon begin to appear as they would on a moonless night. Capturing a scene like this requires careful planning and execution.

Tips for Photographing the Total Lunar Eclipse

There are numerous ways to photograph a lunar eclipse, but here are 5 methods I techniques I suggest you try out:

  • Point-and-shoot digital camera through a telescope eyepiece (eyepiece projection)
  • Smartphone camera through a telescope eyepiece 
  • DSLR camera and wide angle lens on a stationary tripod
  • DSLR camera and telephoto lens on a tracking mount
  • DSLR camera attached to telescope (prime focus) on a tracking mount
  • Dedicated astronomy camera attached to telescope and tracking mount

All of the methods described above are capable of incredible lunar eclipse photos. However, the ones that leverage the full manual control of a DSLR or dedicated astronomy camera will have more creative control over the types of shots available.

 

Wide-angle nightscape images that include a large portion of the night sky including an eclipsed moon can be done using a DSLR and tripod. For a 30-second exposure, a tracking mount is not necessary. At a focal length of 18mm or wider, star trailing will begin to show after about 20-25 seconds, so just keep that in mind. 

To capture the stars and constellations in the night sky, an ISO of 800 or above is recommended. However, this exposure will likely record the eclipsed moon as a featureless ball of light.

To properly capture both the starry sky and a detailed moon, you will need to capture exposures of varying lengths and blend them together into a composite image. This is because the moon is much brighter (even while eclipsed) than the surrounding starry sky.

A composite image can be made be masking the area of your night sky exposure, and blending in a shorter exposure of the moon with surface details. This technique will take some time and experience to master, but the results can be amazing.

I’ll share a few more astrophotography tips a little farther down the post.

Using a DSLR and Telescope

A telescope can provide an up-close view of the eclipsed moon, and will allow you to take pictures of the moon using your camera or smartphone. The prime focus method of astrophotography is best, as the camera sensors focal plane is aligned with the telescope. You can directly attach a DSLR camera using a T-Ring adapter to utilize the telescopes native focal length.

The prime focus method requires that the telescope tracks the apparent rotation of the night sky to avoid any movement in your shots. To learn more about the process and equipment involved for deep-sky astrophotography, have a look at a typical DSLR and telescope setup.

If your goal is to capture an up-close view of the moon during the eclipse, there are many benefits to this technique. A small refractor telescope will have the adequate amount of focal length (magnification), offer precision focus, and a stable base to attach to an equatorial telescope mount. 

To record the lunar eclipse with a DSLR camera, no filters are necessary. A stock DSLR camera is best as the additional wavelengths available with a modified camera are unused in moon photography.

Without a tracking equatorial mount, a 2.5 second exposure like the one above is impossible. Even 1-second of movement at this focal length will record a blurry image if the telescope or lens is not moving at the same speed as the moon.

The benefit of shooting a longer exposure during the maximum eclipse, is that you also record the starry sky behind the moon. To do this in a single exposure on a normal full moon is not possible as the dynamic range is too wide.

A dedicated one-shot-color astronomy camera is more than capable of taking a brilliant photo of the eclipse as well. The computer software used to control these devices have countless options to control the Gain and exposure settings of theses cameras. 

For projects like this, I personally enjoy the freedom and simplicity of a DSLR. Camera settings such as ISO, exposure and white balance can easily be changed on-the-fly as the eclipse is taking place.

Using a Telephoto Camera Lens

A telephoto camera lens with at least 300mm of focal length will also work well. At longer focal lengths like the ones necessary for a close up of the moon, you must use a fast exposure to capture a sharp photo of the moon. This is because the Earth is spinning, so you’re essentially trying to photograph a moving target. 

The image below was captured using a Canon EOS 70D and a Canon EF 400mm F/5.6 Lens. 

partial eclipse phase

The final stages of the partial eclipse phase are challenging to photograph because there is a bright highlight on a small portion of the moon. For the photo below, the camera settings included an ISO setting of 6400, and a shutter speed of 1/8.

A tracking telescope or camera mount such as the iOptron SkyGuider Pro (pictured below) is recommended. An equatorial mount that is polar aligned with the rotational axis of the Earth will allow you to take longer exposures, and get more creative with your camera settings.

Owners of astronomical telescopes for astrophotography usually own a GoTo equatorial mount. This allows the user to enter any celestial object into the hand controller, and the mount will automatically slew to that object once it has been properly star aligned.

The key to capturing details of the moons surface in your lunar eclipse photo is reach, and exposure. By this, I mean that you need enough magnification to show the detailed craters of the moon’s surface, and a fast enough shutter speed to not blow out any of the highlights in your image. 

To do this, a precise exposure length must be used. One that preserves the data in your image while also bringing enough of the shadowed areas forward is ideal. For my photos, I found an ISO of 200 and an exposure of 1/200 to work quite well. This was enough to showcase a starry sky behind the eclipsed moon.

I use Adobe Photoshop to process all of my astrophotography images, including photos of the moon and our solar system. Adobe Camera Raw is a fantastic way to edit your images of the lunar eclipse because it gives you complete control over the highlights and color balance of your image.

With the camera connected to the telescope (prime focus astrophotography), experiment with different exposures and ISO settings in manual mode, using live-view to make sure you have not under/overexposed the image.

The shortest exposures will only be useful during the partial stages of the lunar eclipse, as the lunar eclipse is beginning and ending. As I mentioned earlier, this is a challenging phase of the even to capture in a single shot, as the shadows and highlights of the image are from one end of the spectrum to the other.

When the moon enters totality, you will need to bump up your ISO, and/or your exposure length to reveal the disk of the moon as it becomes dimmer. Use a timer or external shutter release cable to avoid camera shake if possible. Ideally, you’ll keep the ISO as low as possible for the least amount of noise. With an accurately polar-aligned tracking mount, exposures of 2-5 seconds will work great.

Using a Smartphone or Point-and-Shoot Camera

Another way you can photograph the moon is to use the eyepiece projection method of astrophotography. To do this, you’ll simply position your digital camera or smartphone into the eyepiece of the telescope. This method usually requires a far amount of trial and error, but you may be quite surprised with your results.

An eyepiece smartphone adapter may help to steady your shot of the lunar eclipse. Although you’ll have much less control over exposure and record less detail, this technique can be used with a non-tracking telescope such as the Apertura AD8 Dobsonian I reviewed in late 2018. 

The moon is one of the few subjects that is easy to photograph with a non-tracking mount, although the transition phases of the eclipse will be more difficult. I recommend capturing the lunar eclipse during its maximum phase if you’re using this method. You likely won’t be able to capture a well-exposed image  using the cameras auto-exposure mode.

Experiment with your cameras manual settings that allow for variations in shutter speed. 

Without Using a Telescope 

If you are simply using a point and shoot camera, or a DSLR and lens on a tripod, you can still take photo of the lunar eclipse. This is often a great way to capture the landscape and mood of the moment. The photo below was captured back in October 2014 using a CaDSLR Canon EOS 7D and a 18-200mm lens.

The wide angle tripod shot was photographed at 18mm, while the inset image was captured at the lenses maximum focal lengh of 200mm. 

Total Lunar Eclipse - Moon Photography

Just like I mentioned when using a phone camera, you’ll want as much manual control over the camera settings as possible. “Auto” mode, flash, and autofocus won’t work on a photo of the total lunar eclipse. Adjusting individual parameters such as exposure length and ISO is essential when photographing objects at night. 

Practice taking shots at night beforehand, so that you are ready when the eclipse happens. Ideally, find a location that includes some interesting foreground and background details to capture a dramatic scene on the night of the event. 

I hope you enjoy the total lunar eclipse in January with your friends and family. If the weather cooperates, I will be photographing the event from my backyard using a DSLR camera and telescope.
