I don't believe this is noise, so what is it and how do I get rid of it?

So, I'm trying to teach myself time lapse long expose shots so I could really capture the movements of the stars. I haven't done much reading up on it mostly because I could find any good info so I just winged it and I think my first try was pretty successful. For the photo I used a D7100 with an 18-55 wide angle Nikkor lens. I had about a 45 minute exposure time with f/22 and anISO of 100. I'm happy I was able to capture the stars movement but if you zoom in on the attached image, it's covered in a mixture of grey, red, green, and blue dots. I don't believe this is noise and I tried noise reduction using Lightroom buy it didn't do much. Any idea what it is and where I'm going wrong??
