Nightscape Stacker

Free browser beta

Stack the sky.
Keep the landscape.

Turn a fixed-tripod photo sequence into one nightscape. Align and average the stars, keep your reference-frame foreground, and export a 16-bit TIFF for your final edit.

A focused workflow

From your sequence
to your editing desk.

One view, one fixed tripod. Start with the photos you already have.

Mark the sky

Click along the horizon. Refine the boundary with a brush so the ground stays out of the stack.

Inspect, then export

Check the stars and horizon at actual pixels. Save a 16-bit sRGB TIFF and finish in your usual editor.

What to look for

Before you start

A good fit for your photos?

This beta stacks the sky from one consistent fixed-tripod sequence. You draw the sky mask; the foreground comes from your chosen reference frame.

Use

Desktop Chrome or Edge

Bring

3–30 matching frames

Prepare

JPEG, PNG or supported RGB TIFF

Camera RAW files need to be exported first. Tracked skies, panoramas and separate foreground exposures are outside this beta.

File requirements and current limits
Sequence
Same dimensions, framing and exposure settings, up to 32 megapixels per image. At least three frames must pass alignment.
Files & color
8-bit JPEG or PNG; supported single-page 8-bit or 16-bit RGB TIFF with uncompressed or ZIP strip storage. Use sRGB. Unsupported profiles and TIFF variants are rejected; untagged 8-bit files get an sRGB warning. Full file guide
Processing
Photos are processed on your device. Large images need enough memory and free local storage. Keep the tab open until processing and export finish.
Inspect the result
Fine branches, clouds, moving objects and lens distortion can cause seams or doubled stars. The foreground is not denoised. Check the center, corners and horizon before export.

There is no automatic branch masking or trail removal. A 16-bit export from an 8-bit source cannot add original capture detail.
