To fight the noise in the picture I did two things; Decrease the ISO value and simply take more frames. For this image I used 45(!) frames. By far the most frames I made for just one image. The total exposure time is almost 4 hours. The stacking was done with DeepSkyStacker. The final touch-up was done with Photoshop.
