Nice image Terry. to get a darker sky and
TRY to maintain comet detail try....
1. Open image in Photoshop
2. Click Adjustments tab
3. Click Curves Icon
4. On Left Hand side of curves graph Click the
Black Point EyeDropper (Topmost eyedropper of the 3 shown -NOT the grey or white point eyedroppers). The cursor should now change from a pointer to an eyedropper shape. Anywhere on the image where you now click (in the next step) will be the NEW reference level for
BLACK
5. Move the cursor/eyedropper to an area of mid grey in your image and left click the mouse. The sky should be darker and the comet mostly unchanged except for some unfortunate reduction in length due to the vignette in your image.
6. if unhappy with the result, UNDO with Control Z or undo in the EDIT tab top left and try another area, you will soon get the hang of it.
There is a sample below of what's possible.
That was an easy way to do it across the image, but perhaps if you want to maintain all the tail length you could mask or select only the comet or invert select (everything else) and reduce the exposure with a smooth feathered edge. More complicated I didn't try that.
