This tutorial will guide you on how to properly use the Deep Sky Stack feature.

Deep sky stacking is to superimpose deep space images after shooting. Through stacking, the signal-to-noise ratio of the image is improved and a clearer image is obtained.

Using the Deep Sky Stack feature requires connecting your mobile device to the Seestar to access the Seestar's Deep Sky images.

First, click on the "Deep Sky Stack" function on the homepage to enter the "Deep Sky Stack" function, and click the "Add Images" button.

Enter the “Deep Sky Images” page and select the deep sky target you want to overlay. After entering the target folder, select multiple images. When selecting images, try to choose images that are not overexposed, have complete targets, no obstructions, and no drag lines. After selecting, click "OK".

After clicking "OK", you can preview the selected images, and you can also click the "Edit" button in the upper right corner to filter the images again.

Only one deep sky target can be selected for each deep sky stack. If you want to select other targets, you need to clear the currently selected target image first, and then select other target images. Click the "Edit" button in the upper right corner to select all images, and click Delete to clear the images.

After the image is confirmed to be correct, click the "Stack" button to start the deep sky overlay.

After waiting for the stack to be successful, click "Go to check" to view the image after the overlay is completed.
