The NEOWISE comet was discovered by a space telescope built at Utah State University, where I now work. I think that is so cool. When Comet Hale-Bopp passed by in 1997, I was just getting started in my high school photography class. I remember trying to photograph the comet with my black and white film, but my results were not worth keeping.

Hopefully, these tips will help you make a picture worth keeping and sharing with your kids when the next great comet comes around.

1. Don’t buy expensive tools

You could probably make a fair picture with your smartphone, using certain apps, but I’m talking here about using a DSLR or mirrorless camera. In fact, any camera with Manual mode could get it done. There are so many cameras out there that I can’t speak to every model, but these tips should work with most of them.

All you need is your camera, the lens it came with, a fresh battery, an empty memory card, and way to make it stable.

2. Switch to Manual mode

Your camera has lots of presets to help you make a good picture, but it gives up when you point it at the stars. Just switch it to Manual mode, the big “M” on the dial. Use your camera’s manual to help you dial in the following settings.

3. Aperture: f/11, or wider

Set the aperture to f/11. This will help ensure you get a picture that looks crisp and sharp. If you’ve got a faster lens, by all means, use a wider aperture. Depending on your focal length, you may need f/11 to get the foreground in focus as well as the stars.

4. ISO: 3200

ISO determines how sensitive the camera is to light, and a high number is more sensitive. Crank it up to 3200 and you’ll see a lot more stars in your picture than you can see with your eyes. 3200 is pretty high, and the trade-off is that the picture will look a little grainy, a little noisy. It’s OK. It’s better to have a noisy picture than no picture at all.

Many cameras can look good at even higher ISO’s. I shot everything here at 4000 on a Lumix S1.

5. Shutter speed: 4 seconds

Turn the dial on your camera to change the shutter speed to four seconds. What you normally see for shutter speed is a fraction of a second. It may look like 1/250 or it might just say 250. Now turn the dial so it’s slower (1/10s is slower than 1/250s).

When you get down to one second the display will read 1″, which means 1 second. Keep going to 4″.

This is a good place to start, but you can change the shutter speed to make the whole picture brighter or darker. Remember, 8″ is one stop brighter than 4″.

6. Turn on Long Exposure NR

This is key, and you might need to check your manual or Google it for your camera. Long Exposure Noise Reduction makes your picture look a whole lot better by removing most of that noise we talked about above.

The only catch is that it takes twice as long to make a picture. Your shoot for four seconds, then it’s another four seconds before you can see the photo. Be patient, it’s worth the extra time for a better-looking picture.

7. Get composed & focused

Focusing the lens on the stars is probably the hardest part, and it’s not too bad. Start by turning the ISO to its highest setting and setting the shutter speed to about 1/15s (you’ll go back to your other settings in a minute).

With a high ISO and a faster shutter speed you’ll be able to see the picture immediately instead of waiting eight seconds. It’s hard to see through your viewfinder to compose a picture at night, so turn on Live View if your camera has it. That also makes it much easier to focus.

Use the center-most focus point in your viewfinder — it’s the most accurate and easiest to use at night. Try to focus on the edge of the horizon or a far-away tree at the edge of the sky. The camera can’t focus on the stars well, but it may be able to see the edge of a tree against the sky.

Once you get a picture with the horizon in focus, flip the switch on the lens to manual focus so it won’t try to re-focus between shots.

Other tips

  • Use a tripod or a bean bag or a rolled-up sweatshirt on the roof of your car to make the camera stable for four seconds.
  • Turn on the camera’s timer for 2 seconds, or use Shutter Delay mode to allow the camera to stop moving after you press the shutter button.
  • If you zoom in more, the stars will appear to be lines instead of dots because the Earth is rotating while you shoot. Turn the ISO higher and use a shorter shutter speed.
  • Remember: The picture is supposed to be black! It’s nighttime, after all.
  • Be courteous to other viewers and keep social distancing in mind.

When can I see it?

You’ll be able to photograph the comet about an hour after sunset. In Logan, UT, I was able to start photographing at about 10:15 p.m MT. Away from city lights, you might be able to see it sooner. Also, the comet is getting a little smaller as it now gets farther from the sun. But you’ve got some time, and if you’re an early riser you can even photograph it before sunrise in the northeastern sky.

Where can I see it?

To my eyes, the comet is a little brighter than the Milky Way. If you can get outside the city a little bit without major lights to the northwest you should be able to find it pretty quickly. Find the Big Dipper and then scan downward. Binoculars will help, especially if you can put them on a tripod.

A popular place in Cache Valley, UT is at Benson Marina. It’s just far enough away that you can see it with unaided eyes by 11:00 p.m.

But you can see it almost anywhere looking to the northwest in the evening, or the northeast before sunrise. That means you can get creative with foregrounds. Water is nice in the foreground because it gives a little reflection that lightens up the ground. Try light painting with a flashlight, too.

Most importantly

Go see the comet! Take binoculars if you have them and go watch something that doesn’t happen every year. Take the kids or grandkids or the neighbor kids. It’s cool to see and wonder what it has seen as it travels around the solar system.
