SkyChart is a location- and time-accurate sky chart application for round, Garmin Connect IQ 2.4 or later devices. It uses your current GPS position and time to display the night sky, featuring 127 of the brightest named stars, the constellation outlines, the sun, moon with accurate phase, Venus (violet), Mars (red), Jupiter (green), Saturn (yellow), and Uranus (blue), as well bright deep sky objects.

Use Up and Down to show labels for constellations (as abbreviations), the planets, and the catalog number of the deep sky objects.

Use Menu to toggle on/off night mode (draws in red).

TO CHANGE SETTINGS (instructions: https://forums.garmin.com/developer/connect-iq/w/wiki/14/changing-your-app-settings-in-garmin-express-gcm-ciq-mobile-store) to choose these preferences:
- Auto refresh every five seconds (start / stop with activity [red] button)
- Use the current compass heading when refreshing (North will always be up on the initial load of the app)
- Flip East and West as traditional star charts do
- Draw the planets 
- Draw Constellations
- Use the last captured GPS location (will update when you get a good GPS fix)

Note that the first execution requires a GPS fix that may take a while. To ensure it loads, record a GPS activity at your location.

Known issues:
- Labels can be unreadable for objects that are close together, depending on the current compass orientation
