I also have pretty good documentation ever since I started to observe with binoculars, on the 4th of August 1974 at the age of 11. The first target was the Moon, of course
On the 19th of May 1978 - some four years later, at the age of 15 - I experimented with my father's Exakta Varex VX -camera. Attached is the pic with details.
My father is now 97, but back then the scope I used was his DIY-project.
Be well!
