In this situation I next adjust color balance. Mine will have a b&w appearance after DSS processes the images. You may need to increase luminance or saturation of colors once the balance is ok.
See how some noise reduction affects image.
Can try sharpening with unsharp mask tuned to ignore your dark space.
I'm just starting out too....
I've been fortunate to go to some dark skies lately. What is your iso, seems like you have a tracker/piggy back on a telescope if you have 2 minute subs? I found and read an iso of 800-1000 is good. With dark skies at this iso, f3.5, I then have a good exposure at around 4-5 minutes. Not sure what your aperture is, but with a tracker you can stop it down a bit if you have issues with IQ (I don't see any).
Here is one on an astro modified t3i and 20mm lens at f 3.5. About 6 lights and darks, 4-5 minute subs, iso 800. Processed in DSS, then LR4. The reds are more pronounced. I pointed the camera straight up towards the tail of the milky way hoping to catch some meteors during the Perseid shower.
The second one is with a 5DII unmodified, but otherwise the same setup. This looked b&w too at first with DSS. In LR worked on color balance, contrast, and then dark sky luminance slider. Don't be afraid to make what may seem like extreme adjustments compared to a daytime landscape. Vibrancy/saturation can help bring out the nebula colors even with stock camera.
