Easy Long Exposure Camera vs AstroSequence

This app makes it easy to take long-exposure photos with your iPhone. Capture the passage of time in a single image—from city lights, starry skies, star trails, and fireworks to flowing waterfalls and rivers. Choose from three blending modes to create the look you want. 【Light Trails】 Adds up the light from each frame to draw trails from car headlights and brighten subjects that are too dark to see. Perfect for night scenes and faint auroras that are hard to see with the naked eye. 【Motion Blur】 Averages multiple frames to give waterfalls and rivers a smooth, silky appearance. It can create a slow-shutter effect even in bright conditions and can also make moving people less noticeable. 【Lighten】 Keeps only the brightest parts of each frame, so the background doesn’t wash out even during long exposures. Ideal for fireworks, star trails, and auroras that are clearly visible to the naked eye. 【Create from Video】 Turn videos you’ve already recorded into long-exposure photos. Choose the part of the video to use and blend it with Motion Blur or Lighten. Stabilization is also supported. Key Features ・Exposure times from 1 to 180 seconds, plus Bulb mode that you can stop whenever you choose ・Live preview of the blended image while shooting ・Image stabilization to reduce camera shake without a tripod (up to 3 seconds in the free version) ・Post-capture brightness adjustment from −2.0 to +2.0 EV, with the option to save multiple versions ・Auto and manual focus, plus pinch-to-zoom ・Switch between lenses and front/rear cameras ・3-second and 10-second self-timers ・Grid and level tools for composing your shot ・Shoot using the iPhone volume buttons or a compatible Bluetooth remote shutter ・Selectable image quality and JPG saving ・EXIF metadata including exposure time and ISO Great For ・Cityscapes and illuminated night scenes ・Starry skies and star trails ・Fireworks ・Auroras ・Car and train light trails ・Motion blur in waterfalls, streams, oceans, and clouds ・Making moving people less noticeable in busy locations The free version includes all the essential features you need to enjoy long-exposure photography. The Pro version is available as a one-time purchase and adds manual ISO control, ad removal, noise reduction, unlimited stabilization duration with Bulb mode support, full-resolution saving for photos created from videos (the free version reduces the long side to 2048 px), high-bit-depth 16-bit PNG saving, direct saving without the preview screen, and more. Tips for Better Results For standard long-exposure photography, mount your iPhone on a tripod or place it on a stable surface for sharper results. Image stabilization helps reduce camera shake when shooting without a tripod, but the edges of the resulting photo will be cropped slightly. Results and available lenses may vary depending on your iPhone model and shooting conditions.

AstroSequence is your deep-sky imaging coach. Every clear night raises two questions: what should I shoot, and exactly how should I shoot it? AstroSequence answers both — scored against your location, tonight's moon, and your specific gear — then hands you a concrete, time-budgeted shooting plan. No account. No subscription. No ads. The astronomy engine runs entirely on your device; only optional weather and city lookup use the internet. TONIGHT — what to shoot Open the app and see tonight's darkness window, moon phase and illumination, and your top-ranked targets scored 0–100. Each recommendation comes with plain-language reasons and warnings — visibility hours, transit altitude, how close the moon sits to the target, and seasonal timing. Bright moon out? Narrowband-suitable targets are automatically rescued if your rig has the right filter. SHOOTING PLAN — exactly how to shoot it Pick a target and get a complete plan built for your camera and filters: a gain hint, filter allocation, a sub-exposure sequence table, shooting priorities, and a session checklist. Only have 90 minutes? Tell it — the plan is budgeted to the time you actually have. TARGETS — a curated catalog Browse 60 hand-picked deep-sky targets: emission, reflection and planetary nebulae, supernova remnants, galaxies, globular and open clusters, and dark nebulae. Each entry lists coordinates, magnitude, size, difficulty, best months, recommended hours, and recommended filters. PROJECTS — track multi-night targets Set an hours goal per target, log sessions by filter and minutes, and watch your progress fill. AstroSequence tells you what to shoot next by surfacing whichever filter is furthest behind its share of the goal. EQUIPMENT — profiles for every rig Create multiple equipment profiles — telescope, camera (OSC or mono, cooled or not), mount, guiding, and filter set — with autocomplete backed by a large built-in gear catalog. Switch rigs and every recommendation re-tunes instantly. LEARNING MODE Every plan can explain itself. Expand the "why" notes to understand the reasoning behind filter choices, exposure lengths, and target picks — so you learn the craft, not just follow instructions. WHY ASTROSEQUENCE • On-device astronomy engine — recommendations and plans are computed locally • Explainable, deterministic recommendations — every pick shows its reasons • Moon-aware narrowband rescue for bright-moon nights • Time-budgeted exposure sequences fitted to your available minutes • Per-rig equipment profiles • Multi-night project tracking with shoot-next filter guidance • No account, no subscription, no ads, no tracking Optional online features: AstroSequence can pull a free hourly cloud-cover and visibility forecast for tonight, and look up your observing site by city name. These use free, keyless services — your equipment, projects, session logs, and plans always stay on your device. Built for deep-sky imagers who want to spend clear nights capturing photons, not second-guessing the plan.
