Very nice read Chris

I managed to catch CTA 102 visually as well just before Xmas. Prior to that my most distant object was a "mere" 4.5 billion LY's !

I believe CTA 102 is still around mag 13.

Hi John Thanks for your comments.  A snapshot below that I constructed at the time from AAVSO shows how quickly the variability changes.  It was noticeably different using subjective visual observations an hour apart.  I think its incredible we can do this from our backyards.
