I suppose Scopes age, but what they could resolve in the 60-70's is still what they can resolve today, that doesn't change I expect.
One would see exactly what they saw then

Exactly right, spot on.
However, mechanical design, electronics.. all that makes a large difference.
I still have an old 8"f6 cave optical scope that I purchased secondhand in 1985 (my first scope). Still use it at school outreach nights, it has tube rotating rings and the motor drive tracks well for visual but not good enough for astrophotography which is my main interest these days.

That's a nice looking Bosma you have as a guide scope.

It is a surprisingly nice scope for an achromat, 102mm f7, focuser is a bit ordinary but optics are sharp. It doubles as a good terrestrial scope.
