Night Atlas

Point it at any starry photo. Watch it name the sky.

Night Atlas plate-solves your astrophotography entirely on your iPhone and labels it beautifully: constellations, named stars, planets, the Moon, and deep-sky objects — exported at full resolution, with nothing ever uploaded.

Lost-in-space astrometry, in your pocket

You captured the sky. Night Atlas tells you exactly what you caught.

Import a RAW, TIFF, or JPEG nightscape and Night Atlas matches the star patterns in your frame against a built-in catalog of 25,000 stars — typically in about a second, with no network at all. The solution places every label astrometrically: elegant constellation hairlines that stop at your foreground, named stars with soft-halo typography, planets and the Moon computed for your exact capture time. Stitched panoramas and warped composites are declined rather than mislabeled. No account, no uploads, one-time purchase.

Bring your sky

Pick any starry photograph from Photos or Files — 42-megapixel mirrorless RAW files are welcome, and the interface never stutters.

Watch it solve

A progress ring walks through the stages — reading EXIF, detecting stars, matching patterns — while lost-in-space astrometry pins down the exact patch of sky.

Label and share

Toggle constellations, names, stars, planets, and deep-sky objects, set the label density, then export the annotated image at full resolution.

Built around the real workflow

Tools that earn their place.

True plate solving

A lost-in-space astrometric engine matches four-star patterns from your photo against a pattern database compiled from the HYG catalog, then verifies and refines the solution to arcminute residuals — the same class of technique observatories use.

Honest by design

Stitched panoramas and heavily warped composites cannot be represented by a single camera projection, so Night Atlas declines them instead of guessing. A solve is only reported when independent evidence agrees.

Labels that respect the photograph

Crisp typography with soft halos — never boxes. Constellation lines stop at mountains and trees instead of crossing them, labels avoid each other, and a density slider runs from minimal to complete.

Planets and the Moon, for your night

Capture time and location from EXIF drive built-in planetary ephemerides, so Jupiter is labeled where Jupiter actually was — with clear notes in Solve Details whenever the file lacks the data to know.

Built for big files

42-megapixel RAW files ingest smoothly through a memory-safe pipeline, and exports composite at native resolution — what you framed is what you share.

Private by architecture

There is no backend. Solving, ephemerides, and rendering all happen on the phone; photographs never leave the device, and there is no account, no analytics, and no subscription.

Overview

Night Atlas identifies and labels the night sky in photographs. All processing — star detection, plate solving, ephemerides, and rendering — happens on your device.

Solution 7 Media does not collect personal information through the app, sell personal information, use advertising SDKs, use analytics SDKs, or track you across apps or websites.

Your photographs

Photos you choose through the system picker are read on-device to detect stars and solve the sky. They are never transmitted to Solution 7 Media or anyone else.

Night Atlas reads a photo's EXIF metadata (lens, capture time, and location if present) on-device, solely to improve the solve and to place the planets and Moon for your capture moment.

Photos access

Saving an annotated image uses add-only Photos access — the narrowest permission iOS offers. The app can add the images you export; it cannot read your existing photo library.

SupportHelp for naming the night

Your first solve

Tap Upload Photo and pick any starry frame — a single exposure works best.
Watch the solving stages complete; most skies resolve in a second or two.
Use the toggles and the density slider to tune the labels to taste.
Tap Save Annotated Image for a full-resolution copy in Photos, or share it directly.

If a photo will not solve

Night Atlas needs real stars and a single-camera projection. Stitched panoramas, star-trail stacks, and heavily warped composites are declined by design. Hazy or twilight skies with only a handful of stars may also fail — try a frame with a clearly visible star field.

Star reduction is handled; star removal is not. Images processed with moderate star reduction still solve, but starless or near-starless versions (StarXTerminator and similar, or very aggressive minimization) erase the patterns every plate solver depends on. If such an image will not solve, run the version of the photo from before the star-removal step — the solution applies to the same framing.

About planets and the Moon

Planet and Moon labels need the photo's capture date; the Moon is placed most precisely when GPS is present in the file. Solve Details explains exactly what the file provided and what was assumed.
