Possibly the past update. Here is 253 with12hrs total and 37 fresh darks taken with the cooling operating at 45% to reach -15c vs the old ones with the cooling at 83% to hit -15c

Much cleaner overall result. It's probably obvious from this image but I am pushing to reveal the dark dusty regions of 253 with this.

In some deeper images of 253 that I have seen the core of the galaxy seems to have dusty tendrils being ejected outwards (more likely dust being drawn inwards) around the core. I've done my best to show these, and I can see them in there however I feel to be really effective I would need to visit dark skies to run 10+ minute exposures.
