Version 2.1 - Session Pack Starwell 2.1 adds Session Pack, a field-ready checklist for a real night outside. - Session Pack gathers tonight's dark-window summary, Moon illumination, naked-eye limiting magnitude, best deep-sky targets, timeline events, and gear checklist into one compact plan. - Copy the full Session Pack as text or save it as a plain-text file before heading outside. - Target rows show best time, altitude, magnitude, gear guidance, moon-interference hints, and whether the object is already in your observing log. - The pack is built from the same offline astronomy engines as Tonight, Deep Sky, and Sky Events, with new unit tests around limits, gear notes, observed-state carry-through, and export text. - Fresh current-build Mac screenshots and documentation updates are included. Still fully offline. No account, no tracking, no Location Services.

Stars Well 2.0 — a pro upgrade for stargazers, still 100% offline. • Light-pollution-aware sky: set your Bortle class and see your true naked-eye and telescope limiting magnitude, with a Moon-brightness penalty. • Almanac: an ephemeris table for the Sun, Moon, and planets — RA / Dec / altitude / rise / transit / set over any date range. • Altitude-vs-time curves with a true-darkness band for any object. • Conjunction finder: upcoming close approaches of the Moon and planets. • Tonight's Sky Events: twilight, rise/set, close approaches, and meteor peaks, in order. • Reality check: whether a deep-sky object is within reach from your sky and gear. No account, no network — every position is computed on your Mac.

Introducing Tonight's Sky Plan — a darkness-aware observing timeline that finds the true-dark window between twilights, flags Moon interference, and ranks deep-sky targets by their best viewing time tonight. Plus a live sky-dome with VoiceOver support, Messier-marathon milestones, and refined moon-phase accuracy. Fully offline.

Version 1.1 — Deep Sky New in 1.1: go beyond the constellations and plan a real night out under the stars. • Deep Sky — all 110 Messier objects (galaxies, nebulae and star clusters), each with its type, brightness, the constellation it lives in, an original observing note, and clear guidance on whether you'll need just your eyes, binoculars, or a telescope. • Tonight's Best — a fully offline observing planner that ranks every deep-sky target for your chosen place and time, putting the highest, brightest ones first, with rise / transit / set times so you know exactly when to look. • Observing log — mark anything you've spotted with the date, the gear you used, and a note. Track your progress toward all 110 and export your logbook as a text file. It stays private on your Mac — no account, no cloud, no network. • Find targets from a finder chart centred on each object, jump straight from a constellation to the deep-sky objects inside it, and see tonight's best targets right on the Tonight screen. Still fully offline. No account, no subscription, no tracking. Clear skies!
