What is the best ISO for your DSLR for astrophotography?
- http://dslr-astrophotography.com/iso-dslr-astrophotography/
- 1/3 and 2/3 ISO stops. Most cameras offer steps of 1/3 to change the ISO setting. Don’t use those settings for astrophotography, always use ‘full’ ISO stops!. The camera is just scaling your images to mimic these ISO settings. For 1/3 stops, like ISO 125, the camera will simply use the analog amplification of ISO 100 and scale it ...
Best ISO values for Nikon cameras | DSLR …

- In a previous article I explained in detail what ISO does in the camera and what, in general, is the best ISO value to use for astrophotography. It all comes down to finding the ISO value that is the best mix of read noise and dynamic range. Some might wonder about unity gain as well, but you can read here why you shouldn’t worry about unity gain. ...
ISO and Astrophotography | The Best Settings for a Clean Shot

- The Best ISO for Astrophotography: If you’re just looking for the best ISO to use on your DSLR camera for astrophotography, start with ISO 1600. This is often the “sweet spot” for modern digital cameras, and it is my most used ISO setting for deep-sky and nightscape astrophotography.
Best ISO values for Canon cameras | DSLR …

- In a previous article I explained in detail what ISO does in the camera and what, in general, is the best ISO value to use for astrophotography. Basically it comes down to finding the ISO value from which the upstream read noise will swamp the downstream read noise. Any ISO value beyond this one has no additional benefit and only decreases Dynamic Range.
ISO 800 vs ISO 400 for astrophotography | DSLR …

- In the previous article about the best ISO setting for astrophotography, I’ve explained what ISO is, how it works in digital cameras and how to determine the best ISO to use for your DSLR. However, theoretical discussions aside, the question is of course if we can even see the difference in reality? During my stay in Namibia I did a few ISO800 vs ISO400 tests, so …
Best ISO values for Sony cameras | DSLR Astrophotography
- http://dslr-astrophotography.com/iso-values-sony-cameras/
- Unclear. 2 linear trends present so ISO 200 and ISO 1600 both seem plausible. Sony A7R. 100. 13.5. Sony A7S. Unclear, two linear trends present. There seem to be a significant drop in read noise at ISO 2000 so ISO3200 is a good possibility. 10.4 @ ISO 3200.
Understanding ISO for Astrophotography - Sky & Telescope

- Richard S. Wright Jr. Instead, ISO is short for the Greek word isos, which means equal (see the bottom of this page for more on this). This term is incredibly useful in photography. Not that long ago, film was the medium of photography, and ISO 200 film was twice as sensitive to light as an ISO 100 film. ISO 400 was twice as sensitive again, etc.
Choosing the Best (Good Enough) ISO for Astrophotography
- https://skyandtelescope.org/astronomy-blogs/imaging-foundations-richard-wright/choose-iso-astrophotography/
- Test It Out. Adjusting the exposure is little more than a linear scale of the image in Camera Raw. Richard S. Wright Jr. I shot 10-second exposures at f/1.4 at all the ISOs from 100 up to 6400. Right out of the camera, the lower ISO images were naturally very dark and the higher ISO images were progressively brighter.

- Use a wide-angle lens at its widest f/stop (lowest f/number) and focus manually on a bright star using live focus, if the feature is available with your camera. Zoom in on the live-focus view to help achieve the sharpest focus. Set the ISO speed to 1600 and expose for 30 seconds.
How to Find the Best ISO for Astrophotography: Dynamic …

- The Canon EOS 6D, still one of my favorite choices for a DSLR for astrophotography, is highly ISO-variant and actually shows its best low-light noise performance at ISO 6400 and higher!
