5. Operating the Astro Module
5.1 Astrophotography Modes
- Go-To Star Function:
Within the app, navigate to the astrophotography section. Select the "Go-To Star" option. You can search for specific celestial objects (stars, constellations, planets) or choose from a list of visible objects based on your location and time. The Polaris will automatically orient your camera to the selected object.
- Astro Panorama Mode:
This mode allows you to capture wide-field astrophotography panoramas. The Polaris will automatically move the camera to capture multiple overlapping images, which can then be stitched together in post-processing to create a high-resolution panoramic image of the night sky.
- Long Exposure Photography:
The precise tracking capabilities of the Astro Module are ideal for long exposure astrophotography, minimizing star trails and allowing for greater light collection from faint celestial objects.
5.2 Remote Control and Monitoring
The smartphone app provides comprehensive control over the Polaris and connected camera. You can adjust settings, monitor live view, and initiate captures remotely. This is particularly useful for astrophotography in cold environments or for maintaining a stable setup.
- Live View: Access your camera's live feed directly on your smartphone.
- Settings Adjustment: Control exposure settings, ISO, aperture, and other camera parameters from the app.
- Precise Movement: Use the app's interface for fine-tuning camera position with extreme accuracy.
