How to Photograph Deep Sky Objects like Galaxies and Nebulae

Open the Seestar App and select Stargazing Mode on the homepage to enter the Objects.

In the Objects, you can search for specific objects, view tonight's best celestial targets, or browse categories like galaxies, nebulae, and star clusters. Once you find an object of interest, tap the locate button next to it to pinpoint its position on the star map. Then, click the GoTo button to automatically direct Seestar to the target and begin shooting.

During GoTo, the screen displays the angular distance to the selected object. When the distance shows 0.1 degrees, Seestar will capture an image to verify whether the position is correct.

If GoTo is stuck at 0.1 degrees or shows a failure message, it is usually due to the focus not being set to infinity or an obstruction in the lens's line of sight.

Check for obstacles: Look along the direction of the telescope tube to ensure there are no walls, trees, or clouds blocking the view. If obstacles are present, try selecting a different target for GoTo.
Verify focus: If no obstacles are found, exit GoTo mode and check the focus by observing the star points on the screen. If out of focus, cancel GoTo, tap the AF button on the right side of the shooting screen, and wait for autofocus to complete before retrying GoTo.

In focus

Additional Notes
Seestar comes with a preset focus value for stargazing, which it automatically adjusts to upon startup for user convenience. However, environmental factors like temperature may cause slight deviations in focus. In such cases, follow this guide to readjust the focus and manually update the default value for future use.
