Stack your nightscape photos.
Right in your browser.
Choose a fixed-tripod sequence, mark the sky, and align the stars while keeping your reference-frame foreground. Export a 16-bit TIFF to finish in Lightroom or your usual editor.
Planned launch: free to preview. $19.99 once to export. Plus applicable tax; no subscription.

From a sequence to a TIFF.
Use your own photos, or try the clearly labeled synthetic sample to learn the controls.
Mark the sky
Click along the horizon, then refine with the sky brush and eraser. Save a project to keep your mask and frame selection.
How to draw the boundaryStack and inspect
The browser aligns and averages the sky in linear light. Check actual-pixel crops of the center, corners, and horizon before exporting.
What to check in the resultYour photographs are not sent to a processing server. Local working files may be used while stacking; keep this tab open until export finishes.
Check the sequence first.
This beta handles one consistent, fixed-tripod view. A sharp result starts with sharp source frames.
- Browser
- Desktop Chrome or Edge. Large sequences need enough memory and free local storage; mobile browsers are outside this beta.
- Sequence
- 3–30 photos, matching dimensions and exposure settings, up to 32 megapixels per image. At least three frames must pass alignment.
- Files
- JPEG and PNG with 8-bit source data; supported single-page 16-bit RGB TIFFs, including uncompressed and ZIP strip storage. Camera RAW requires an export first.
- Color
- sRGB processing and an embedded sRGB profile on TIFF export. Unsupported profiles are rejected; untagged 8-bit images are interpreted as sRGB with a warning.
Known limits
You draw the sky mask manually. Fine branches, moving clouds, water, and lens distortion can still produce seams or doubled stars. Some regions may lack enough stars to validate alignment; check the image as well as the report.
Tracked skies, panoramas, mixed exposures, and separate blue-hour foregrounds are outside this beta. The reference foreground receives no multi-frame noise reduction. Exporting an 8-bit source into a 16-bit TIFF does not add original capture detail.
Start with photos you already have.
The guide covers file preparation, manual masking, actual-pixel inspection, exports, and project recovery.
