How to reduce noise without loosing detail?

After having 15 photo's in a row rejected I'm getting quite demotivated. I get to hear that there is excessive digital noise. First I don't see this, but maybe that's because I'm originally an astrophotographer and there noise is often 1000x higher... Problem is that I just don't know how to get rid of it without loosing too much detail. Attached I have an image that according to screening has too much noise.
If anybody can point me in the right way, or share a good workflow that would be very, very welcome...
Thanks!

Well, the sky looks a bit grainy. (not excessive though)
What you want to do is select the sky and apply noise reduction only to the sky. I'd recommend software called Nik Collection which offers best noise reduction in the market (in my opinion) So just use selective noise reduction and sharpen the planes only. (as you know, sharpening brings in noise)
It also seems like you've lost red color. (you need to use "save for web" option in photoshop because this website messes up colors if you do not do so)
I'd try smaller res for that photo. probs 1200x800 or 1440x960

I always use Topaz noise reduction as part of my workflow, I always denoise every photo regardless before i sharpen it, works for me |

GEvening!
Peter Brauns, I'm not entirely agree. If we use the lowest ISO (in this case, 100), the camera forces us to slow down, which in some cases is extremely slow for photography is completely blurred. Therefore it is necessary to balance ISO, Speed and Aperture. And of course, do all this manual settings in your camera.
And always watching the meter.
Andre, my advice is easy. Shoot in RAW. Use manual mode. With good light conditions using low ISO, and increases progressively poor (not much) so you do not force photographs make very slow (sometimes it is fantastic to capture movements of propellers, etc). Always look at the meter for measuring light...and ENJOY!
