Astro (Aurora, moon, star trails, planets) - can you attach your camera to a telescope? . This is NOT about anything above the horison so no only clouds, sunset.
There are some technical guidelines to calculate exposure times
Many night photographers use the 500 or 300 Rule to calculate exposure times. It calculates the maximum exposure time for your lens focal length before the stars will start to blur. Use these settings as a starting point, actual exposure times may be influenced by foreground brightness and light pollution.

So practice the below to get some understanding and repeat this when you are out on location:
Working with Shutter Speed
In manual mode, set the lens aperture as low as possible—ƒ/2.0, ƒ/2.8, or ƒ/4.0
Set the ISO to 12,800.
- Photograph the same night scene at 20, 10, and 5 seconds.
- Set the ISO to 6400 and photograph the same scene at 20, 10, and 5 seconds.
- Set the ISO to 3200 and photograph the same scene at 20, 10, and 5 seconds.
- Set the ISO to 1600 and photograph the same scene at 20, 10, and 5 seconds.
Members suggestions: astrophotography, ‘Above the horizon’ Clouds, aurora, moon, sunset etc. Its certainly a specialized area that takes a bit of doing at times! Night Photography (astro, light trails)
