Align: This synchronizes the scope to coordinates of the selected object. The bullseye indicated in the sky chart shows where the telescope thinks it is pointing. If that appears incorrect, the scope and the software must be aligned. To do so:
- Physically center the scope on a real object in the sky.
- Select that object in the sky chart to make it the current target object.
- Tap the Align button.
You can re-align the scope and the software anytime there is a discrepancy between the two.
Note: for Celestron NexStar and Orion/SkyWatcher SynScan telescope controllers, tapping the Align button stores the offset between the telescope's reported position and the selected object's position. It subtracts that offset from the telescope's reported position whenever the telescope is within 10 degrees of the object you Aligned on. In other words, SkySafari performs a "local sync" around the alignment target. If you move the telescope to a very different part of the sky, you may want to Align on a target in that part of the sky. Also note that the telescope's RA/Dec reported by SkySafari will differ from the RA/Dec reported by its hand controller (since SkySafari is applying the alignment offset to the telescope's reported position.)
确保首先用手柄或slew把望远镜指向校准目标,然后才在Sky Safari Pro里选择目标校准。
