Lunark turns your iPhone telephoto into a moon camera that actually works on the night you need it. Point at the moon, tap once, and a few seconds later the photo on your screen is sharp enough to share. No ISO charts to learn, no tripod hunt, no spinning processing screen that loses the moment. - One tap captures and stacks five frames into a clean handheld shot - Handheld stacking holds up at high zoom, so you can leave the tripod at home - Exposure is set from tonight's phase, not from the black sky, so the moon is not a white blob - Tonight's shooting window tells you when the moon is high enough to be worth a long lens - Phase, altitude, and illumination are computed on device and work fully offline - Export full-quality files for the shots you want to keep Privacy Policy: https://docs.google.com/document/d/e/2PACX-1vTDX9pxPOlUJl_skVUHPi99mAw0y2B2BYd_v1mJkoF3xW3rlOcW5KlYd4t93MMbbGhctSTnBTy7d_l6/pub Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Turn a sequence of frames into a cleaner, richer imageβ€”entirely on your iPhone or iPad. Celvion Stack gives photographers a complete local workflow for importing RAW/DNG or standard photos, inspecting frames, aligning, stacking, editing, and exporting without a computer. SIX PURPOSE-BUILT STACKING MODES NIGHT Combine multiple exposures to reduce random noise while preserving natural detail and color. MILKY WAY Align the sky and foreground separately so stars can remain sharp while the landscape stays stable. LIGHT TRAILS Blend selected frames into continuous, controlled light trails. SMOOTH WATER & CLOUDS Build a long-exposure look from a sequence, with smoother motion and flexible control. MOVING DISTRACTION REMOVAL Suppress people, vehicles, and other transient elements that appear in only part of the sequence. LANDSCAPE Merge aligned frames for a cleaner, more detailed landscape result. PRO MILKY WAY CONTROL Choose a reference frame, review per-frame quality scores, refine sky/foreground masks, and reject trails from aircraft and satellites, plus other intermittent light streaks, before stacking. RAW LENS CORRECTION When a matching lens profile is available, correct geometric lens distortion. Automatic vignetting and chromatic-aberration correction are not currently included. FULL-RESOLUTION EXPORT Export the final stack as JPEG, PNG, 16-bit TIFF, or 10-bit HEIF, then save it directly to Photos or Files. ON-DEVICE AI On supported devices running iOS 18, use local AI denoise and 4Γ— super resolution. Core stacking works on iOS 17. PRIVATE BY DESIGN Processing stays on your device. Your photos are not uploaded.
