What is the rule of 500?

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.

Thereof, How long does it take to get exposed to the Milky Way?

To start, try a 10-second exposure time. After you try 10 seconds, experiment with longer exposure times to get even more light in your shots, like a 30-second exposure or even longer. However, one con of long exposure settings is capturing “star trails” while shooting the Milky Way as it moves across the night sky.

Accordingly, How do you shoot stars without trails?


Star Photography – Setting Up the Shot

  1. Choose a location for the photo shoot that’s away from light pollution. …
  2. Mount your camera to a solid tripod. …
  3. Remove your camera strap from your camera. …
  4. Select exposure settings to maximize the quality of the shot. …
  5. Set your lens to manual focus and focus it at infinity.

Is a 50mm lens good for astrophotography? Therefore, the 50mm f/1.8 STM works excellently for portraits. … For astrophotography, I would not recommend using the Canon 50mm f/1.8 STM at its wide open setting of f/1.8, as it greatly distorts stars at this setting, especially in the corners of the full frame.

Also know What is the 300 rule in photography?

The 300 Rule for Crop Sensor Cameras

So a 16mm lens is effectively 26mm on a crop sensor, rounding up. Using the same lens examples as above, a 16mm focal length lens on a crop sensor camera works out to just over 18 seconds maximum exposure, 300/16 = 18.75.

What is the best lens for photographing the Milky Way? But what makes for a good lens when it comes to shooting the Milky Way? Ideally you want a wide-angle zoom or prime; it’s best to work in a focal range of around 14-20mm in 35mm equivalent terms (so about 10-14mm on APS-C or 7-10mm on Micro Four Thirds based camera).

Can you see Milky Way with naked eye?

More than 100,000 light years in diameter, with more than 100 billion stars and at least as many planets, the Milky Way is arguably the most impressive feature of the night sky that you can see with the naked eye. … Then you’ll need a clear night sky with little to no fog or humidity.

What is the 500 rule in astrophotography?

The 500 rule is used to measure the maximum exposure time you can shoot before the stars become blurry or before star trails appear. Setting the shutter speed for longer than allowed by this rule will result in images that do not have sharp stars.

How do you shoot star trails with a DSLR?


How do you focus on star trails?

  1. Set your camera lens to manual focus.
  2. Adjust your camera focus as close as you can to the infinity symbol.
  3. Set your shutter speed to 30 seconds.
  4. Set the lowest aperture setting your lens supports.
  5. Then set your ISO to 1600 and take a picture.

Can you change ISO while shooting film?

Even if you are using a newer camera, double check to make sure that you and the camera agree on the ISO value:) PS: Note about digital SLRs – the cool thing about Digital SLRs is that you can change the ISO settings anytime. If you shoot film you are stuck with one ISO setting for 36 frames.

Can you shoot stars with a 50mm?

Star stacking and separate foreground exposure. Shutter speeds should be limited to 10 seconds or less at 50mm on full frame, and as low as 3 seconds for very sharp pinpoint stars.

Is 35mm good for astrophotography?

If you’re planning to do nightscapes, with the Milky Way above and landscape below, a 35mm lens may be too narrow. In my experience, the 35mm focal length is just wide enough to capture the core of the Milky Way with a sliver of foreground. I normally use a 14-24mm lens for my nightscape photos.

What focal length is best for astrophotography?

Focal Length

For landscapes or astrophotography, wide angle lenses that span at least 16-24mm are preferred in order to capture as much of the scene as possible. However, you’ll likely want to avoid ultra wide-angle fisheye lenses that are typically in the 8-10mm range, as these lenses result in distorted images.

What is the 500 rule in photography?

The 500 rule is used to measure the maximum exposure time you can shoot before the stars become blurry or before star trails appear. Setting the shutter speed for longer than allowed by this rule will result in images that do not have sharp stars.

What is the 600 rule?

The rule states that the maximum length of an exposure with stars that doesn’t result in star streaks is achieved by dividing the effective focal length of the lens into the number 600. A 50mm lens on a 35 mm camera, therefore would allow 600 / 50 = 12 seconds of exposure before streaks are noticeable.

What is the F 16 rule in photography?

The f 16 or Sunny 16 Rule states that, on a bright sunny day at noon with your aperture set to f16, the reciprocal of the ISO setting is the correct shutter speed. If the ISO is set to 100, your shutter speed should be 1/100 or as near as you can get to 1/100. At ISO 200 the shutter speed should be 1/200.

Is a 28mm lens good for astrophotography?

The Sony FE 28mm f/2 is an optical surprise. From a standpoint of sharpness, bokeh quality and aberration performance, the lens is excellent. For astrophotography, the lens performed very well with the stars, even wide-open at f/2.

Is 20mm good for astrophotography?

When Sony announced the 20mm 1.8 G, it seemed to tick all the boxes: it’s compact but not too tiny, has an ergonomic design, is lightweight with a fast aperture, competitively priced and the quality looked very promising. …

Is f4 fast enough for astrophotography?

Focusing the lens is a straight forward process at 24mm, and even offers a little forgiveness at an aperture of F/4. Faster lenses that can open up to F/1.8 are beneficial for astrophotography but often result in a challenging focus routine.

Where is the darkest place on Earth?

The measurements revealed the Roque de los Muchachos Observatory as the darkest place on Earth, where artificial light only brightens the night sky by 2 percent.

Can you see Andromeda from Earth?

Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see. At 2.5 million light-years, it’s the most distant thing humans can see with the unaided eye. Astronomers sometimes call this galaxy Messier 31, or M31.

How do you shoot a Milky Way with a smartphone?

However, photographing in low light conditions can be a bit tricky. To help you out, here are 5 simple tips to capturing beautiful images at night with your smartphone.


  1. Get out of the city. …
  2. Use a tripod. …
  3. Get the right app. …
  4. Avoid flash and HDR. …
  5. Steer clear of digital zoom.

Is f5 good for astrophotography?

Most lenses work best when stopped down a bit, therefore for me f5 or f5. 6 seemed to work best. … I have managed to get some good images with the lens at f4 and this may be necessary if it is a very dark night. It’s probably better to go to f4, before heading above an ISO of 3200.

Can you use a 500mm lens for astrophotography?

Often the “Rule of 500” or “Rule of 600” is brought up to suggest that you can take short exposures of the night sky without any trailing, and still produce images. … To produce good images we need as much light as possible. The rule of 500 is only a bandaid on the real problem.

What is the best time for astrophotography?

Facing south during April and May the pre-dawn hours are best. From June to early August the best time is near midnight, though the Milky Way will be visible almost all night. From Mid August through September the best time is soon after the sun has set and the sky has grown dark.
