Found an astronomy book from 1837 with instructions on how to build telescopes and drawings of the moon surface.

That is fantastic. Where did you find it?

@SortOfTested a family friend I know. She's got a whole library of old books. Including the complete original collection of Heinrich Heine, an assortment of german literature and an anniversary edition of mein kampf. Lol. She said I could have the astronomy book

@Fast-Nop damn it, took me a while. In printed form it's easier and you get used to it after a page or two

So how do you build the telescope? Does it say how to grind a lens?

Ah ja, die Wunder des Himmels.
Werden wa wohl nie verstehen

Can you post picture of drawings?
