When "Save Each Image" is enabled, the Seestar currently saves both the FITS file and a JPEG version (plus its thumbnail) for every frame.

For users who perform their own post-processing, the FITS files are usually the only files that matter. In my case, I routinely delete all the JPEGs immediately after copying the data to my computer.

It could be useful to add a small option next to "Save Each Image" allowing users to choose what to save:

☐ FITS + JPEG (current behavior)

☐ FITS only

This would reduce storage usage on both the device and the mobile device, especially during long imaging sessions where hundreds or thousands of frames are collected.

The current behavior would remain the default, while advanced users who only need the scientific data could save considerable storage space.
