    What you will create -

    These directions are posted at the registry also under the galaxy filter page from sambrookjm.
    I asked him to add a few features to the filter to create these effects.

    Let's begin the tutorial -
    Create a new document with 1920×1200 pixels (72 dpi) and fill canvas with color #000000
    Make a new layer above the black one and fill it with pure white color (#ffffff).
    We have now two layers: the black one and the white above it. For the layer with white color we change the Layer Blending Mode to Dissolve, layer opacity 1% (no more than this amount) and get something resembling space.

    The next step is the critical one - this creates each dif new galaxy nebula cloud arm
    Create a new transparent layer name it nebula - paint the strokes.

    Then a whirl and pinch

    rotate to your liking and apply motion blur

    Then whirl and pinch again

    Set the perspective

    Time for some color-
    Create three new layers - name them nebula-colors 1,2, and 3, and change the layer Blending Mode to Color.
    Grab the paint brush tool - Set the opacity of the brush to 10.0, and the scale to your liking - use the circle fuzzy 17 brush - select the color - 5a78cc
    Select your new nebula-colors layer1 and paint over the galaxy like this
    first layer -

    change color to #ff0000 to add red color
    second layer - nebula 2
    [​IMG]

    change color to #fff000 to add yellow color
    third layer - nebula 3
    [​IMG]

    of course the colors could be optional.
    Now just add the center core or bright spot. :) a white circle in a yellow one two layers
    Blur and set opacity to each at your liking -

    Here is one i just did with those exact directions except i added a dup layer of nebula clouds and set that duplicate layer to dissolve for a more intense ring feel.

    You can of course then set that layers opacity to your liking.

    Thanks for checking out the tutorial.

    I grabbed some brushes from O at Gimp Chat and used them with a gradient with full color spectrum - pretty cool.
