This appears in the upper-left corner of the chart, and enables chart location changes without entering a specific location or target.
| Icon | Action | Description |
|---|---|---|
| Back to Earth | Set the source location to the Earth. Same function as the Earth icon in the star/DSO details. | |
| Up | Increase chart center declination/altitude ("look up") | |
| Down | Decrease chart center declination/altitude ("look down") | |
| Left | Increase chart center right ascension/azimuth ("look left") | |
| Right | Decrease chart center right ascension/azimuth ("look right") |
The Earth icon is most useful when you're viewing the sky from stars other than the Sun. If you've been poking around a bunch of faraway stars and want to get back home quickly, hit the Earth icon.
The arrow icons retarget the chart to new coordinates in the direction specified by the arrow. Specifically, it recenters the chart on a specific right ascension (RA) and declination (Dec) determined by the spacing of the chart coordinate grid. Each step equals 2 grid spacings in the given direction. For example, at the lowest zoom level for Atlas charts, the declination spacing is 15 degrees. The Up and Down arrows will change the chart's center by +30 or -30 degrees in declination.
