thank you all for your comments,

Pete those links were fantastic, what a great write up and set of drawings!
Incredible shots Pete W!
Thanks!
Here is another go, I definitely achieved more this time than the initial rough go.
Forgive the artifacts and onion rings, clearly a low dynamic range set
I also find that:
Almost no time elapsed between AVI 1 and 2, 2 moons visible.
Some time elapsed between AVI 1/2 and AVI 3, one moon disappears behind
Jupiter and a wide FOV/ framing reveals a more distant 3rd moon.
This might help me nail down the night.
I know, from what was recorded either side of the original VHS tape that
it was in the week following the Sunday night special on 60 mins ( a link later
of that great episode)
The 60 mins special with the late , great Gene Shoemaker, was on or around the night
after
the biggest fragment impact, so that would put it around Sun 24th July or later.
I recorded Apollo 11 25yr anniversary news items on the same tape in the preceding week.
Not a very accurate documentation of such a memorable recording eh


I know I would have written it all down somewhere but it is long gone.
It will be a bit of fun trying to narrow it down.
I'm not sure if Stellarium moon predictions are very accurate winding backwards that far
but I have a few candidates for the moon arrangement
so far.....will keep the thread posted.
