MySkyPics organizes astronomy experiences and makes them easy to share with others. • Add smart telescope photos into a sky object focused photo album. • Add observations without a photo as a Sighting. ASTRO PHOTO GALLERY Start by picking an object in the app and add its photo from your Camera Roll. MySkyPics is designed to hold photos of thousands of sky objects — sun, moon, solar eclipse, lunar eclipse, planets & moons, comets, meteor showers, asteroids, dwarf planets, stars, star clusters, galaxies, and nebulae - including all Messier and Caldwell objects. It even has a special place for photos of objects not included in the app, labeled ‘My Objects’. As a photo is added for a sky object, it is instantly tagged with that object’s tags. Any custom tag(s) you’ve created can also be attached. Expand your record with optional place and notes. Objects added to the album can be quickly found with Search and browsed with a swipe. SIGHTINGS RECORD Sightings makes MySkyPics a reference resource of your astronomy experiences. Because not all astronomy viewing can be recorded in a photograph, Sightings is a special option for recording details of observations without photos. Record the details of a sighting — date, confidence, magnitude, opposition, place, notes, and tags. WEB RESOURCES Most sky objects also link to a Wikipedia article with more information on the object. Many also have links to a NASA ‘Picture of the Day’ article. (Internet access needed to access these links.) One can also add Wikipedia and NASA links for sky objects that are added to the app.

AI CometStack is a breakthrough comet alignment app designed specifically for mobile astrophotography workflows. Overcome the long-standing tradeoff of comet movement during long imaging sessions.

Core Features Motion-Aware Stacking: Aligns the comet nucleus across time while preserving star geometry. Two-Path Automation: Integrates stars and comets separately, then blends them on-device. Batch Processing: Handles full-night capture sets with uniform parameters. Pro Format Support: Works natively with FITS, RAW, TIFF, PNG, and JPEG files. Mobile-First Flow: Real-time previews and guided steps built for iOS deep-sky sessions. Simple Workflow Import your exposure frames (or use the included sample files). Let the app automatically track and model comet motion. Validate and adjust the seamless background blend in real time. Export gallery-grade, press-ready images instantly from the field.
