Eagle Image Stacker vs Struix

Eagle Image Stacker is a local-first astronomy imaging toolkit for iPhone. Import or capture RAW, DNG, ProRAW, JPEG, HEIF, TIFF, and other supported image files, then align, calibrate, stack, inspect, and export high-quality results. Use Astro Mode for star fields, galaxies, nebulae, and deep-sky sequences. Use Planets Mode for Moon and planet workflows with ROI tracking and alignment tools. RAW Converter helps inspect and export camera files, while calibration tools support dark frames, flat fields, hot-pixel review, masks, and alignment analysis. The app is built for on-device processing. Your selected images and generated outputs remain local unless you choose to save, export, or share them through iOS. Some capture features depend on your iPhone hardware. RAW and Apple ProRAW availability varies by device.

Your camera has the sensor. Your iPhone has the processor. Struix brings computational photography — the multi-frame merging phones do automatically — to the RAW files from your real camera, entirely on device. Import a shoot over Wi-Fi, from an SD card, or your Photos library. Struix automatically finds the bracket and burst sets in it and merges each one the right way, in a single tap — no lining up frames by hand, no desktop. WHY IT'S DIFFERENT • Automatic. It detects your exposure brackets and bursts and picks the right merge for each — you don't sort, pair, or select anything. • More than HDR. Bursts merge into a cleaner, lower-noise frame; exposure brackets merge into wider dynamic range. One tool for both, not just tone-mapped HDR. • A real computational pipeline. A raw-domain, multi-frame merge — the class of technique behind modern phone cameras — not a filter or a simple blend. • Standard DNG out. Every result is a tiled DNG that opens in Lightroom, Pixelmator, and other RAW editors, ready to finish. TUNED FOR YOUR CAMERA Deeply tuned for OM SYSTEM and Olympus — detection, color, and rendering are calibrated to the bodies enthusiasts actually shoot. It also imports and merges RAW from many other cameras via your Photos library or an SD card. MADE FOR THE MOMENT Everything runs on your iPhone — no cloud, no account, no cables, no computer. Merge on the train right after the shoot.
