How do you take long exposure photos of stars?

In order to achieve longer exposures than 15-25 seconds during the night, you can lower the exposure and use a narrower aperture. For example, you can aim for an ISO of 400 and aperture of f/8 – adjust the shutter speed accordingly and you’ll most likely have a nice star trail when you’re done.

How long should exposure be for stars?

Exposure Time / Shutter Speed Shutter speeds ranging from 20-90 seconds are the best for star trails photography. I use a technique that takes a few hundred-star images, without trails, and overlays them on top of each other, creating a star trails image.

How do you take a long exposure shot in the night sky?

To photograph the stars in the sky as pinpoints of light, start with as wide an f/stop as your lens allows, and shutter speed of about 20 seconds. Any more time than that and the stars will begin to blur. Increase the ISO as needed for a good exposure.

How long should you expose astrophotography?

You want to use a long exposure time (slow shutter speed) when doing astrophotography, this will give your camera’s sensor enough time to record those little dots of flickering light. Usually, a good place to start is somewhere in between 20 seconds and 30 seconds.

What settings should I use to photograph stars?

Best camera settings for stars

  1. Exposure mode: Manual or Bulb mode.
  2. Aperture: f/2.8 or as fast as your lens allows.
  3. Shutter speed: 15-30secs.
  4. ISO: 800-1600.
  5. White Balance: Auto.
  6. Focus: Manual.
  7. File type: Raw.
  8. Self-timer: Enabled, 3-10secs.

What is the 500 rule?

The 500 Rule It recommends that your shutter speed is equal to 500 ÷ Equivalent Focal Length. So, if your full-frame equivalent focal length is 20mm, the 500 rule would suggest that you use a shutter speed of 500 ÷ 20 = 25 seconds.

Do you want high ISO for astrophotography?

ISO 3200 is a good starting point, though you may need to adjust down to ISO 1600 if there is a lot of ambient light or light pollution or you start to see more noise than stars. Very dark skies may require you to boost the ISO to 6400, but I wouldn’t recommend going higher than this.

Why are my star photos blurry?

There are two primary reasons for this: not using a fast enough shutter speed and not having the stars properly focused. In the video below, we learn from photographer Matthew Saville with NatureTTL how to address both these concerns and capture sharp nightscapes.
