Alpha fade out problem

Hey,
I`d like to fade out a lot of nodes and geometries by putting an alpha node before the rest. But while fading out the alpha value, I can see through the objects. How can I fade down the alpha value so it fades to the background and doesnt allow to see through all the objects?

you need to render all of these nodes into a rendertarget...and now fade just the rendertarget

Thank you for your reply.
The problem is, I`ve got an earth model with multiple semitransparent hulls. Its in a slide and the background is outside of this slide in the background world.
If I use a rendertarget, the result looks different, probably because the transparency calculations dont include the background color, since it is not one of the objects that are behind the render target.
What can I do, to make it look like it does without a rendertarget?

Check the Texture Node which is bound to the render target and set the Shading Property to NoAlpha.
