ISO and Astrophotography | The Best Settings for a Clean Shot
- https://astrobackyard.com/iso-astrophotography/
- When trying to decide on the best ISO setting to use for your next astrophoto, take a few test shots using anywhere from ISO 400 to ISO 6400 and inspect the results. Using ISO 800 for a 30-second exposure is often a good place to start and can be adjusted depending on the amount of light pollution present and/or the f-ratio of your camera lens/telescope.

- The data that is read out of the sensor is normally amplified before being digitised usually with 12 or 14 bits. Up to some ISO value – which varies from camera to camera – the gain of the amplifiers is increased by powers of two as the ISO is increased from say ISO 100 to ISOs 200, 400, 800 and possibly 1600.
What is the best ISO for your DSLR for astrophotography?

- 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 digitally to match ISO 125.
Choosing the Best (Good Enough) ISO for 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.

- 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.

- Now optimum level is around ISO 1200 if there was such a thing. At this point, each electron level gets mapped to a single bit. However, since we don't have ISO 1200, ISO 800 or ISO 1600 would be the best solution. Of course, dynamic range does decrease by a factor of 2 everytime you double ISO setting.
What Camera Settings Should I Use for Astrophotography?
- https://www.adorama.com/alc/what-camera-settings-should-i-use-for-astrophotography/
- For deep-sky astrophotography, your ISO levels should generally be set high and support your other exposure settings. For some, 800 or 1600 works in bringing out the moon and stars during long-exposure shots of dark night skies. You can opt to go higher than that if your camera is one that excels in low light conditions. Turn Autofocus OFF
