Create a new document with size of 1300×800 px and fill it with white (feel free to use your own size and color). Press Cmd/Ctrl+Shift+N to make a new layer. Hit G to active Gradient Tool, choose Radial Gradient with color #022240 and #093b62. Drag a line from the top to bottom to get result below:


Step 2

Open star background pack. I choose “starry 1″ and use Move Tool (V) to drag it into our canvas and change the mode to Color Dodge 100%:


Step 3

To change color of some stars I use an adjustment layer with Clipping Mask. On stars layer, go to Layer-New Adjustment Layer-Channel Mixer:


You can see some stars redder:


Step 4

Place aurora image onto the sky and change the mode to Screen 100%:


Click the second button at the bottom of Layer panel to add mask to this layer. Use soft black brush with low opacity (around 20%) to reduce some light on aurora sky. You can see how I did it on the mask and result on picture:


Step 5

Duplicate this layer, flip it horizontally (Edit-Transform-Flip Horizontal) and move to the right.
