About

Read full description

An app for visual astronomy — observing through a telescope or binoculars with your own eyes. · Sky chart — 5.5 million stars with your own fields of view overlaid, opened from plans, observing and object pages. · Plan and recommend — only what your aperture can show under your site's sky (1,272 objects judged in advance), placed into hour slots, rehearsed on the chart. · Observe and record — step through objects on the chart, check, rate and write; review by night or by object. ■ A built-in sky chart · About 5.5 million stars to 13th magnitude and 16,000+ deep-sky objects. Drag and pinch anywhere. · Sky as it looks right now (zenith up) or north up — one tap on the compass at top left. · Build fields of view from your telescope, eyepieces and finder and overlay several at once. Plan objects as rings, observed ones checked. · Open the chart from a plan, the observing screen or an object page, and come straight back. ■ One unbroken night · Plan — added objects settle into hour slots on their own; drag to rearrange. Tap an object for its altitude curve and suggested magnification right there. · Rehearsal — walk the night on the chart before you leave. Course editing handles hour slots, order and start stars on one screen. · Observing — step through objects on the chart, check them off, rate and write notes. Dictate by voice. · Records — enter the night's conditions once, then review by night or by object. Long-term plans spanning months, too. ■ Data and learning · 2,400+ visual guides — how to find it and what each aperture shows. 4,600+ observing points to rate. · Lists such as Messier, Caldwell, Herschel 400 and 1001, plus your own lists and courses. · Star hopping with 126 routes (using the chart's field-of-view settings); Messier marathon prep and a 110-object night. ■ Also Night mode (red screen, shake to toggle, automatic after sunset) · six themes · sketch albums · eyepiece-view simulator · tonight's clouds and seeing · real-time planets · spreadsheets in and out, full backup · on a bigger screen at starnotearchive.com · Korean, English and Japanese. Free. No ads, no purchases. No account in the app; make a web account only if you want the website. Records stay on your phone; only what you send goes up to the web (site names visible only to you). With weather on, the forecast point's location is passed to the weather service. The 13th-magnitude star data downloads only when you ask. Made as a hobby by one observer.
