Best-nights ranking
Upcoming nights scored on moon, altitude, and weather.
Now on iOS · Android coming soon
Plan it.
Compose it. Shoot it.
The astrophotography companion that takes you from "which night?" to a camera firing the perfect sequence — planning, real exposure simulation, and reliable remote control in one app.
The problem
Four apps, one cold night.
Today you juggle a planner, a planetarium, and a trigger app — then re-enter your settings a third time at the camera, in the dark. Nothing carries your intent to the shutter. AstroOwl is one coherent workflow instead.
How it works
One sky. Three modes. One intent.
The same live GPU planetarium carries continuously from Plan to Compose to Shoot — so the framing you choose never jumps.
01 · Plan
Know the night before you drive.
Pick a goal — Milky Way core, Andromeda, a star-trail. AstroOwl shows the sky exactly as it'll look, the target's 24-hour trajectory arc, and a ranked list of the best upcoming nights. Shoot Tuesday, not tonight.
- ◆ Best-nights ranking — moon · altitude · weather
- ◆ 24-hour trajectory arcs with a live "now" marker
- ◆ Multi-target Plans — a named itinerary for the night
Pick a goal, not a catalog entry. Every target ships with its own night-scoring model and exposure presets tuned for it — so the ranking and the starting settings already fit what you're shooting.

02 · Compose
See the exposure before you shoot it.
Your camera + lens's exact frame over the live sky. Pick a technique, dial in ISO / aperture / shutter, and press play — AstroOwl simulates the real exposure, frame by frame: trails, stacking, noise. Then save it as a recipe.
- ◆ GPU exposure simulation — trails, stacks, real noise
- ◆ Sharp-star (NPF) guidance for your exact gear
- ◆ Save framing + settings as a reusable recipe
03 · Shoot
Tap once. Let the night run.
AstroOwl auto-reconnects to your Sony over Wi-Fi (one QR scan to pair). One tap fires your saved recipe; the camera runs the sequence natively while AstroOwl tracks live progress — frame count and ETA — right on your phone.
- ◆ One-tap recipe firing — no re-entering in the dark
- ◆ Camera-native intervalometer with live progress
- ◆ Auto-reconnect + QR Wi-Fi pairing
Feature highlights
Everything the night needs.
Real GPU sky
A 9,000-star planetarium you can pan, zoom, and scrub in time.
Trajectory arcs
A target's full path — rise, peak, set — drawn on the sky.
AR sky preview
Hold your phone up: live camera view with the target's arc overlaid, scrub time to follow its path.
Exposure simulation
Watch trails, stacks, and noise build up before you commit.
Sharp-star (NPF) guidance
The longest shutter that keeps stars pin-sharp for your gear.
Recipe library
Save settings + framing as recipes, then fire them on the real shoot.
Camera-native intervalometer
On cameras that support it, sequences run on the body itself — far more reliable.
QR Wi-Fi pairing
Scan the camera's QR code to connect — no manual password entry.
Auto-reconnect
Silently re-establishes the camera connection on launch and in the field.
More to come
Works with your Sony Alpha
Deep, validated control on a7-series bodies. More camera brands on the roadmap.
Why AstroOwl
The shot you rehearse is the shot you fire.
One coherent, reliable flow replaces three apps and the mental glue between them — your recipe carries from Compose to the camera with nothing re-entered.
