Long-Exposure Astrophotography
- https://www.naturescapes.net/articles/techniques/long-exposure-astrophotography/
- Simply going out any night to image will not do – which night you choose is quite important. To get truly dark skies, you need to take your images at new moon or very close to it. The ideal time window is between the last quarter moon and new moon. …

- Long exposure astrophotography began in 1880 when Henry Draper took a 51 minute exposure of the Great Orion Nebula. He used a tracking mount to take this photo. The German Equatorial Mount is a popular choice and it was first used in 1824. The creation of Joseph von Fraunhofer for the Great Dorpat Refractor.
How Astrophotographers Shoot (Very) Long Exposures

- If you’ve viewed deep-sky astrophotos (not landscape astrophotos), you may have noticed that extremely long exposures (not counting mosaics) are used. In extreme cases, exposures may run over 12
Long Exposure Vs Image Stacking For Astrophotography
- https://nightskypix.com/astrophotography-stacking-vs-long-exposure/
- Long exposures and image stacking are different techniques that serve different purposes. If you are doing astrophotography, you will need to combine the needs for collecting enough signal from the sky with long enough exposure and the needs to reduce the captured noise and boost details with image stacking.

Long Exposure and Astro-Photography Using Raspberry Pi
- https://www.instructables.com/Long-Exposure-and-Astro-Photography-Using-Raspberr/
- Astrophotography is the photography of astronomical objects, celestial events, and areas of the night sky. Apart from recording the details of the Moon, Sun, and other planets, astrophotography has the ability to capture objects invisible to the human eye such as dim stars, nebulae, and galaxies. This fascinated us because the results obtained are breathtaking and can be …
Astrophotography: How Long Can You Go? - Sky
- https://skyandtelescope.org/astronomy-blogs/imaging-foundations-richard-wright/astrophotography-rule-of-500-how-long/
- You can use the "rule of 500" to determine how long your camera can expose before stars begin trailing. But in reality, how long you can expose depends on your focal length, pixel size, and where you are pointing in the sky. Richard S. Wright Jr. Rule of 500 (or 300) If you've never heard of the Rule of 500, it's quite simple.
Longer exposures versus multiple shorter exposures
- http://dslr-astrophotography.com/long-exposures-multiple-shorter-exposures/
- In case of a dark sky, the gains in SNR while exposing longer is quite big in the beginning and reaches a 10% improvement already at 3,5minutes exposures compared to 30sec exposures. The improvements tail off quickly as well though, reaching only a further 1% improvement at 8 minutes compared to the 30sec exposures.
The Complete Guide to Long Exposure Photography
- https://expertphotography.com/long-exposure-photography-complete-guide/
- Once you learn to take basic photographs, it is time to try some more creative techniques. Long exposure photography is a technique where you use slow shutter speeds to create cool effects. This technique can be used to create a wide variety of images, whether landscapes, cityscapes, star photographs, or more.
More short exposures or fewer long exposures
- https://www.amateurastrophotography.com/more-short-exposures-or-fewer-long-exposures-which-is-better/
- As the signal is increased with longer exposure times, the noise will increase to the value of the square root of the signal. In other words, if the exposure signal increases by 100 times, the noise would increase by 10 times – the square root of the signal increase (giving an increase of 10% noise).
