Eagle Image Stacker vs SolarTrack

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.
