My BOLD. Some DSLR has on camera noise reduction setting for astrophotography. Plus post process to further reduce noise. Your image is very good in that department.
I've used in-camera long-exposure NR for star trails - 30s and longer exposures, but haven't seen that type of noise for sub-second exposures. Lightroom does wonders - the raw images are pretty ugly....
