Astronomical photographers often take multiple images of the same area of the sky and stack them on top of each other to increase the signal to noise ratio. This is especially important when photographing faint objects such as galaxies and nebulae. In this article, I will show you how to stack Milky Way photos in Photoshop.

To stack Milky Way photos in Photoshop, you will need to open all of the images that you want to stack in Photoshop. Then, go to the Layer menu and select New > Layer from Files.

In the dialog box that opens, select all of the images that you want to stack, and click Open. Photoshop will now create a new layer for each image.

Next, go to the Edit menu and select Auto-Align Layers. In the dialog box that opens, select the Reposition option and click OK. Photoshop will now automatically align all of the layers.

Finally, go to the Layer menu and select New > Layer from Background. This will create a new layer that is a composite of all of the other layers. You can now adjust the opacity of this layer to control how much of each image is visible in the final stacked image.

PRO TIP: When stacking Milky Way photos in Photoshop, it is important to use the “Lighten” blend mode for each layer in the stack. If the “Darken” or “Multiply” blend mode is used, the photos will become too dark and will not accurately represent the Milky Way.

In this article, we have shown you how to stack Milky Way photos in Photoshop. By following these steps, you can easily create a composite image that brings together multiple images of the same area of the sky.
