How to photograph the Lunar Eclipse (Blood Moon)

Tonights lunar eclipse will be the last for quite some time. It will be visible across most of Europe and America. The totality will be around 1 hour , while the whole eclipse will almost take 3 hours. During the totality phase, the moon is going to have a bright red color, hence the unofficial name "Blood Moon".

Why does it occur?

Usually we would see the moon in a white colour, as it reflects the light caused by the sun. During an eclipse, though, the moon enters the shadow of the earth. In the earths atmosphere blue light is filtered out, meaning that the bypassing light, which is reflected off the moon will be red.

How to photograph the lunar Eclipse?

What you will need for photographing the Milkyway:

- A DSRL or mirrorless camera, where you have the ability to set manual settings

- A tripod that keeps your camera steady during longer exposures.

- A lens that has a high aperture of at least f/5.6, better would be f/4 or even as low as f/1.4

- A lens with 200-400 mm focal length for close ups, you can go wider as well if you wish.

- Clear Skies, check the weather forecast. Small clouds could ruin the shot!

- Make yourself familiar when the moon rises and sets at your place!

What settings do I need?

That's a hard question, and I will tell you why. During the eclipse the moon changes from white and bright to dim and red, meaning that you will have to adjust the camera during the eclipse. When photographing the standard full moon I usually start off with something like 1/300 to 1/400 of a second, wide open aperture and a low ISO, like 100. Especially when shooting with a 400mm lens you will need a fast shutter speed, if you want your images to be sharp. If you have a tracking mount you can expose for longer, of course. I suggest that you start off with the above settings and then just play around and see what works best with your camera and lens!

Once the the eclipse goes towards totality (the phase where the moon is way dimmer), your exposure can well be up to 1-2 seconds. Don't shoot longer than that, and rather increase your ISO to ensure sharp photos!

Things to consider:

If you want to shoot the whole eclipse, be prepared, as it almost takes 3 1/2 hours. So pack something to snack and to drink, and ensure that you've got enough batteries and storage. Last time I photographed the eclipse I filled two 64 GB SD cards.

The Lunar eclipse is a stunning astronomical occurrence and really easy to shoot. I wish you guys all the best of luck, especially weather wise. And don't forget to look up and take it all in!
