Email sent to support@startrailstacker.com is not currently routed to a reader. Do not use it yet; this page will change when a received message and reply have been verified.

If a sequence will not stack later

When support opens, please do not send the photographs. They are yours, they are large, and the useful diagnostic details fit in a short message:

the camera, and the file format you exported (JPEG, PNG, TIFF, WebP, 8-bit or 16-bit);
how many frames, and roughly what resolution;
what the page said — the exact wording of the message, and which stage it stopped at;
the browser and operating system.

If the tool refused because of memory, the message includes the number it needed and the number it was offered; those two figures are the most useful thing you can send.

If something on the site is wrong

The measured claims here are checkable and the underlying data is public. If a number looks wrong to you, record which one and why so it can be investigated when support opens.
