Historical imaging data ???

[Skipper Billy]

I am giving a presentation in the New Year about Astro - Imaging.

Towards the end I want to show 3 images of the same target - one from 30 (ish) years ago - one taken recently by me - one by Hubble to show the progress made and the leap in quality that digital cameras provided.

I seem to remember a website from which I could download images or subs from way back from professional observatories (Siding Spring?) - from digitised film plates.

For the life of me I cant find it now I need it !!

Anyone come across this or a similar resource ??

Thanks in advance.

Actually, now I'm not on my phone I see my first link isn't what I thought it was!  This might be more useful http://tdc-www.harvard.edu/plates/ ?
