Using Astronomy Apps with Telescopes
Pairing astronomy apps with telescopes enhances both tools greatly. Apps can reveal what celestial objects will be in your telescope’s field of view on a given night. And telescopes let you view closer details of objects identified with your apps.
Here are some tips for using apps and telescopes together:
- Use the app to first find targets and note their coordinates. Then point your telescope to those coordinates.
- Ensure your smartphone and telescope are accurately synced by date, time, and location.
- Take advantage of AR features that overlay objects onto the camera view in tandem with your telescope.
- Apps with magnitude limiting let you filter out faint objects not visible through your telescope.
- Record through-telescope images and match them to star charts in your app.
Astronomy apps unlock the full capability of telescopes for amateurs. Let them guide you to awe-inspiring sights through your telescope that you might have otherwise missed!
