The top image has 110 minutes of exposure time, while the bottom has only 75 minutes. The color layers on the bottom image were shot at 2x binning to help with the lack of blue sensitivity. The blue frames were so bad that I couldn't use a centroid on them, and had to manually place the reference points in each frame. The red and green layers were blurred considerably in order to get them to more or less match the blue layer. The luminance was shot at 1x binning, and was sharpened before stacking. The yellow star above and to the left of the core was used as the color reference when the color was balanced. Conversion to LRGB was done with 110% saturation.
