Nicely framed CC. One problem with this one is that the back ground is pretty noisy and I'm guessing you have tried sharpening the stars which has otherwise worked well. Try this - make a duplicate in a new layer. Choose the dust and scratches filter and apply to the duplicate until the stars disappear. Select difference as the blend mode. The stars will show up. Select them using the Select/colour range tool. Under select choose modify expand and select 3 pixels, under the same menu feather by 2 pixels. Paste the selection into a new layer then delete the duplicate background. Call your new layer "stars". You can apply sharpening to this layer and a blur to your background to reduce noise. Then flatten the image.
