If you ever visit Florence make time to see the Museo Galileo.

 

...

The lower telescope in the middle picture is the one that I based mine on. This was primarily because the dimensions and lenses were suitable to making a replica. The longer one has a 1330mm FL and I couldn't find a lens that was close to that. (The shorter one has a 980mm FL and 1000mm FLs are available). At nearly 1.5m length it's also a bit unwieldy.

 

The literature suggests that the upper scope was a research tool and may be the one he used to make observations for Siderius Nuncius since it is dated to 1609. The lower one is dated 1610 and is clearly a fancy version (leather wrapped with decorations). He may have sold some of the fancy ones and presented them to influential people to convince them of the validity of his work.

4" f/10 made for my son, officially complete. Tube is a 6" cardboard shipping tube rescued from the trash, covered on fabric and soaked in shellac.

Focuser is 3d printed hralocal crayford (inspired by Pierre lemay). Spider, mirror cell, and tube end rings also printed.

Mount is made from leftover cabinet plywood, 1/2".

Wrist weights for balance. Kept as low to ground as possible so my son doesn't need a step stool. Although it might need a platform as he grows up...d0ae4b487c3b9c511f943858be2fc84b.jpgc4408e257acf18a6b7bbb576dc662fc9.jpg

Here's a link in Classics, to my version of the Galileian fancy scope, including source for lenses used.

Still working on mount.
Also found a 1300mm fl singlet to try the "workhorse" version, but have not tested it yet.

Looks awesome! Congrats!

Any chance you have your 3D designs published already?

I didn’t build this, I managed to win it in an estate sale auction. Whoever built this did a beautiful job. However, I’d like to eventually make this 14” beast a truss tube design. Any and all advice is welcome!

Learn sketchup and scale this down to a 14”
