Astrophotography: the big picture
Written by
Maya Okonkwo I've seen dark skies firsthand in the Atacama altiplano, Namibia's NamibRand Nature Reserve, and Morocco's Merzouga dunes; every other destination I write about is built from measured Bortle and SQM data, cloud climatology, and primary sources like park services and the International Dark-Sky Association.
Astrophotography starts with a gap most guides skip: the sky a camera records and the sky your eyes see are not the same picture. A sensor can stay open for 1 to 30 seconds and stack faint light into one bright frame, while your eyes work in real time. Why Don't Northern Lights Look Like the Photos? explains the rod-and-cone science, and it is where I would start before spending money on kit.
For the Milky Way, the order of decisions matters more than the camera. How to Photograph the Milky Way puts the calendar first: shoot within five to seven days of a new moon, from a sky at Bortle 4 or darker, during galactic-core season. Only then does it split by device, whether a smartphone in Night mode, a DSLR or mirrorless body, or a smart telescope that stacks for you. On a camera, use the NPF rule rather than the old 500 rule.
Aurora work fails in different places. How to Photograph the Northern Lights argues that a slow kit lens and a flimsy tripod ruin most aurora photos: a sharp f/2.8 frame on a solid tripod beats a blurry f/1.8 frame on a shaky one. Cold adds its own cost, since battery performance drops 30 to 40% below -10°C.
A phone on a tripod works under a bright aurora, but a faint one needs a dedicated camera with a fast prime lens. Decide which sky you are chasing, then buy for it.

ReadFrequently asked questions
Is it worth shooting RAW for aurora photos?
Yes. RAW keeps the full bit depth the sensor recorded, so the subtle colors of an aurora survive into editing. Oxygen produces deep reds rarely visible to the naked eye but reliably captured by modern sensors, and nitrogen adds blue and purple fringes along the lower edge of a bright display. JPEG processing in-camera discards those gradations before you ever open the file.
When should I schedule a Milky Way shoot?
Shoot within five to seven days of a new moon. Once the moon is more than half lit, its glow washes out the core's contrast even from a genuinely dark site. From the northern hemisphere, core season peaks between May and August, with a longer window running from February through October. Check a moon-phase calendar before you check the weather forecast.
Do I need a tripod to photograph the Milky Way with a phone?
Yes. A tripod is not optional: even the steadiest hands introduce blur at a 15-second exposure, and none of this works handheld. Set ISO between 800 and 1600, switch to manual focus, and tap the brightest star in frame, because autofocus hunts and usually fails in near-total darkness.
Does the camera body or the lens matter more for aurora photos?
The lens. Kit lenses that top out at f/3.5 to f/4 give up a lot of light next to f/2.8 (at f/4, roughly half), which forces either high-ISO noise or a shutter so long that a moving aurora blurs. A crop-sensor body with a fast f/1.8 prime still outperforms a full-frame body behind a slow kit lens.
How do I check my exposure once the aurora is overhead?
Check the histogram, not the preview screen, because camera displays are bright enough to make an overexposed image look correct in the dark. If the right edge is hard against the wall, shorten the shutter by one stop. If the histogram sits too far left and the image looks muddy, add a stop. Fire with a remote release.
