Yeah... I'm sorry but some people are just a liiittle too perfectionistic he he . The amount of aberration present in that "before" shot would be unnoticeable in a final image after a a multi frame additive process across the sky, especially if a meridian flip is incorporated...

Still, if you can be bothered and are not worried about pulling your $8K scope apart a little ... hey, knock yourself out I suspect nobody will notice the improvement unless you pointed it out with close up comparisons

That said, given the seemingly fickle vulnerability to the phenomena, sounds like there would be a lot of FSQ's out there that would suffer from this very minor, variable aberration issue caused by slightly miss aligned elements... but it is all but invisible in final images.
