Nice image, Justin. The balance does look too blue on my monitor too. If you want to adjust star saturation without changing the background you need to select the stars separately and then operate on them only. Try Select - Colour Range - highlights. This will get the brightest stars (or you can do Colour Range - Sampled colours - click the eyedropper on the stars and adjust the degree of fuzziness to get more or less stars). At this point you can optionally feather the selection so there's not an abrupt transition between the selected and non selected areas. (Select - modify - expand by 4 pixels, feather by 2 pixels).

To increase saturation I'd suggest (Image - Adjustments - Match Colour - Intensity) rather than the saturation slider. After that you can invert your selection (Select - inverse) giving you the background sky, and adjust the colour balance to reduce the blue, or desaturate it a little.
