How to plan eclipse photos
An eclipse happens on a particular date. Whether you can see it from your chosen spot and include a foreground is a separate question.
01Choose the observing location
Find your actual shooting position on the map. Location makes a major difference, especially for a solar eclipse. A list for your home is not a plan for your travel destination.
02Choose a visible eclipse
Open the three-dot menu (…) and tap “Eclipses”. Use the filter icon at the top right to choose “Visible from here” and, if needed, “Solar only” or “Lunar only”. The list requires the full version. Tap a suitable event.
The eclipse list is calculated for the selected location. 03Check its course above terrain
Look at the phases and skyline in the detail view. Hatched sections are below the horizon or behind terrain. Check more than the maximum: part of the event may already be hidden.
The detail view shows the course and timing of the eclipse. 04Switch to the 3D view
Scroll down in the detail view and tap “View in the 3D sky”. Celeris jumps to the deepest phase visible from here. Pinch to adjust focal length and check the foreground. Move the time before and after maximum as well.
Further down, “View in the 3D sky” opens the deepest phase visible from here. 
The 3D preview combines the eclipse phase with your camera frame. 05Prepare your plan and equipment
Save the view and allow time for travel and setup. Solar photography requires a suitable solar filter securely mounted in front of the lens. Eclipse glasses do not replace a filter on a camera, binoculars or telescope.
The preview does not replace a safety plan. Lunar eclipses do not need a solar filter. For solar observing, follow the linked safety guidance; ordinary ND filters are not a substitute for suitable solar filters. NASA guidance for safe solar viewing ↗
