Welcome to Eise.app
Eise.app is a free browser-based planetary image stacker for astrophotography. Upload a SER, AVI, or MP4 video of Jupiter, Saturn, Mars, the Moon, or the Sun, and it uses lucky imaging - combining the sharpest frames - to produce a detailed final image. Runs entirely in your browser using WebGPU. No install, no upload, no signup.

Under the hood, Eise.app automatically analyzes, crops, centers, and ranks every frame, then aligns and stacks the best ones. After stacking, the post processor opens for wavelet sharpening, RGB alignment, and color adjustments.
- SER or AVI files for stacking + post processing. Multiple files open batch mode.
- Video files (MP4, MOV, etc.) for stacking + post processing.
- Image files (TIFF, PNG, JPG) for stacking, or a single image to go straight to the post processor.
Tip: For Moon or Sun surface closeups, select "Surface" mode to handle larger frame-to-frame drift.
