The noise from the blocked-out star noticably decreases in 2017. Is that due to changes in the stars' activity cycle, or is that due to better processing/capture technology?

I do not know, but my best guess would be an improved post processing algorithm was introduced.

		Wouldn't you just post-process all images again at that point?

I believe it's because the star's brightness does fluctuate, so activity cycle based?
