ISO and Astrophotography | The Best Settings for a Clean Shot
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.

How to Find the Best ISO for Astrophotography: Dynamic Range and Noise
In order to find the best ISO to use for astrophotography, I recommend doing an ISO-invariance test. Most of the samples shown in this article up to this point were made with an ISO-invariance test. It’s a super easy test to run: all we need to do is to take about 7-10 RAW photographs, one at each whole-stop ISO and then we match the exposure brightnesses in post processing. This test is easier to perform in a low-light scenario so I recommend doing this test outdoors at night …

Choosing the Best (Good Enough) ISO for Astrophotography
If the noise drops, then your camera is ISO variant. Even ISO variant cameras will become invariant (ISO-less) at some point, and that’s the ISO you want. In my Canon 5D Mark III’s case, ISO invariance kicked in at ISO 3200, although it was hard to see the difference between the ISO 1600 and 3200 images. I also did this with my modified T3i, and it was hard to tell the difference between photos shot at ISO 800 and ISO 1600. As they say, your mileage may vary.

What is the best ISO for your DSLR for astrophotography?
The ISO on DSLR cameras is probably one of the most misunderstood settings and people don’t seem to agree on the best values to be used for astrophotography. I’ve seen articles and people recommending anything between ISO100 and ISO3200 for exactly the same camera. This is very unfortunate, especially since choosing the best setting can make quite a difference in your end result.

How to Find the Best ISO for Astrophotography: Higher ISO settings …
ISO is gain applied across the light sensing diodes in your camera’s sensor. The higher the gain, the fewer photons that have to hit the sensor to make an exposure in a given amount of time. If you hold aperture and shutter speed constant, you will get more noise as ISO increases. -3 Continue this thread level 1 KittenSwagger

selecting the ‘best’ iso setting – sorry here we go again
This is my first post so please be gentle with me.I have done a lot of research first; honest I have!I have only been active in astronomy for about 6 months. It is only even more recently that I have been trying to get into astrophotography. However, like the rest of the people on this forum I am…
