You don't need the bells and whistles... OTA only is fine. I've got mine for A$2500 shipped from UK and custom fees paid

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.

Good to see you have your scope on an old classic mount, Ariel. I have a GPD of the same vintage - smooth, accurate and utterly reliable.

Hi,

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.
Cheers Rick

Perhaps not surprising that many of these older ones are reflectors. Good to see they're still being used.

Picked this up in December, a 1978 C8 OTA and fork mount, and a mid/ late 80's celestron tripod.

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.
