Astrophotography Guide: How to Photograph the Milky Way in Merzouga

The Sahara's dry air, high elevation, and complete lack of city light make Merzouga one of the more reliable places on Earth to actually see and photograph the Milky Way rather than just hope for it. Most nights out here are clear, and once you're a short walk from any village lights, the galactic core is visible to the naked eye as a genuine band across the sky, not just a faint smudge. This guide covers when to go, what to bring, and how to get a shot worth keeping.

When to go

The galactic core is best placed for Northern Hemisphere viewing roughly April through September, with May to August as the strongest window. Within that, the moon phase matters more than the calendar date — aim for new moon plus or minus three days, or plan to shoot after moonset or before moonrise, since even a half moon washes out the fainter parts of the core. Apps like PhotoPills or Stellarium will tell you exactly when the core rises and how it's oriented on your specific date, which is worth checking in advance rather than guessing on the night. Ask your guide or camp host about local timing too — they'll know when the sky is genuinely darkest on a given night, independent of what an app assumes about horizon obstructions that don't exist out here.

Gear that actually matters

You don't need a huge kit, but a few things make a real difference. A camera with full manual control and reasonable high-ISO performance is the baseline — full-frame sensors have an edge in low light, but a good APS-C body will still get you a usable shot. Pair it with the widest, fastest lens you have, ideally in the 14-24mm range at f/1.4-f/2.8, since a wider aperture lets you use a shorter shutter speed and avoid star trails. A sturdy tripod is non-negotiable on sand, where anything less stable picks up vibration from wind or footsteps nearby; bring a remote shutter or use the camera's self-timer to avoid touching it during the exposure. A headlamp with a red-light mode keeps your night vision intact and doesn't ruin the frame for anyone else shooting nearby, and it's worth packing spare batteries, since cold desert nights drain them faster than you'd expect even in a warm-season trip. A microfiber cloth for dew on the lens and a genuinely warm layer round out the list — desert nights are cool even when the day was hot.

Camera settings to start from

There's no single correct setting, since it depends on your specific lens and sensor, but this is a solid starting point to dial in from: manual mode, aperture as wide as your lens allows (f/1.4-f/2.8), shutter speed of 10-20 seconds (the NPF rule, calculated in PhotoPills, gives a more precise ceiling than the older "500 rule" if you're shooting a high-resolution sensor), ISO somewhere in the 1600-6400 range depending on how much noise your camera tolerates, and white balance around 3500-4200K if you're not shooting RAW — though shooting RAW means you can adjust this freely afterward, which is worth doing anyway. Set focus manually: use live view, zoom in on a bright star, and adjust until it's a tight point rather than a blob, then leave the focus ring alone (taping it down helps if you're prone to bumping it in the dark).

Composition in Erg Chebbi

What separates a good Milky Way shot in the Sahara from a generic one is almost always the foreground. A curving dune ridge leading the eye up into the core, a silhouette of a camel or a nomad tent (ask your guide for a safe, respectful setup rather than wandering off to find one yourself), or simply the wind-etched ripples in the sand under low, raking light all give the frame something the sky alone doesn't. A human figure with a brief, dim headlamp adds a sense of scale that's genuinely hard to convey otherwise — just keep any light source low and brief, both to preserve everyone's night vision and out of basic courtesy to anyone else shooting nearby.

A simple field workflow

Arrive before full dark and scout your composition at twilight, while you can still see the terrain clearly enough to judge framing. Set focus on a bright star before it gets properly dark, shoot a few test frames at high ISO to check composition and exposure, then capture a series of five to fifteen frames if you want to stack them later to reduce noise (Sequator and Starry Landscape Stacker are both reasonable free or low-cost options for this). If you want a cleaner foreground, shoot it separately at blue hour with a lower ISO and blend the two exposures afterward — it's a bit more editing work, but it noticeably improves foreground detail that a single high-ISO night frame can't capture well.

In post, keep edits restrained: raise exposure gently, add contrast and dehaze sparingly, nudge white balance toward neutral or slightly cool, and apply noise reduction with a light hand rather than smoothing the sky into something plastic-looking. Selective texture or clarity on the Milky Way band itself, rather than globally, tends to look far more natural.

Safety and etiquette

Tell your camp or guide your plan and roughly when you expect to be back before heading out to shoot, even if it's just to the next dune over — it's a genuinely easy place to lose your bearings in the dark. Bring water and a warm layer regardless of how hot the day was, keep gear protected from blown sand, and stay well back from dune edges, since the drop and the soft sand below it are harder to judge at night than you'd think. If other people are shooting nearby, keep your light use to an absolute minimum — a phone screen at full brightness fifty metres away is enough to ruin someone else's long exposure.

Planning a trip around it

The easiest way to actually get a proper night of shooting in is to build it into a desert stay rather than trying to arrange a one-off outing — being already at camp after dinner, with your gear set up and a guide who knows the darkest, most sheltered spots nearby, makes a real difference. Our 3-day astrophotography and stargazing tour from Marrakech is built specifically around this: dedicated night-sky shooting sessions, guidance on settings and composition for the dunes, and a sunset camel trek and camp stay worked into the same itinerary, so the photography is the point rather than an afterthought tacked onto a standard desert night.
