Understanding ISO for Astrophotography - Sky & Telescope
- https://skyandtelescope.org/astronomy-blogs/imaging-foundations-richard-wright/astrophotography-understanding-iso/
- These sensitivity standards allowed you to know that for X amount of light, and a focal ratio of f/x and such-and-such shutter speed, ISO 800 would give you a good exposure. This worked no matter whose camera or lenses (or brand of film) you used, and it made photography comprehensible, repeatable, and predictable.
What is the best ISO for your DSLR for astrophotography?
- http://dslr-astrophotography.com/iso-dslr-astrophotography/
- The best ISO for astrophotography for any DSLR is the lowest ISO level from which either a.) the upstream noise swamps out the downstream noise OR b.) the amplification will be done digitally in camera, whatever value of both is the …
Choosing the Best (Good Enough) ISO for Astrophotography
- https://skyandtelescope.org/astronomy-blogs/imaging-foundations-richard-wright/choose-iso-astrophotography/
- When I advise someone to shoot at ISO 1600 or 3200 for astrophotography, that’s really just a zero-order approximation. This month, we're going to take that up a notch with just a little bit of data you can gather for yourself. Recall from past blogs that changing the ISO does not really make your sensor more sensitive.

- For astrophotography use, there is absolutely no point in using an ISO beyond that when the amplifier gain is a maximum. Using a higher ISO that this will simply increase the brightness of all parts of the image equally as, for example, the stars.

ISO 800 vs ISO 400 for astrophotography
- http://dslr-astrophotography.com/iso-800-iso-400-astrophotography/
- ISO is just amplifying the thermal noise that is already there, just as it amplifies the signal. So there is no impact on SNR. Thermal noise is dependant on the exposure time, where longer exposures means more build up of the thermal noise. (and of course the temperature of the sensor) Reply Dodi August 31, 2015 at 6:43 pm
Astrophotography for beginners & shooting it on a DSLR
- https://www.adobe.com/creativecloud/photography/discover/astrophotography.html
- Higher ISO settings will result in brighter images, but they will also increase the graininess of your images. For astrophotography, you want to keep the ISO as low as you can, while still enhancing the light sensitivity, in order to keep your images of the sky as crisp and clear as possible.
Astrophotography, Pixel by Pixel: Part 3 - Gain/ISO and …

- One of the common aphorisms of astrophotography is that everything has trade-offs, and increasing the gain/ISO is no exception. While it is nice to be able to fill the pixel-bucket faster, the downside is that you will have fewer total levels to read off on the pixel.
