I think that the background color is excellent. On my images, I can get the background to a somewhat dark grey. I've been told by a professional astronomer that the background color (Milky Way landscapes) that I have been getting is as good as you can get.

In terms of the small blue and red dots, they are hot pixels. You can remove them within the camera - check page 112 in the K1 manual. It's the Wrench 4 menu page.You can also address them in post-processing with varying degrees of success.

I had to download the image and then bring it up in a viewer in order to zoom in to see the red/blue pixels.
