You guys are dumb
Zacharias Janssen and his son Johannes (Hans), spectacle makers in Holland, are usually credited with inventing the first compound microscope in about 1590. (Hans Lippershey, a spectacle maker in the same city, Middelburg, Netherlands, also claimed credit for the invention but was perhaps more instrumental in the creation of the telescope.) It was said that the Zacharias Janssen was experimenting with ways to improve spectacles for people who needed greater magnification to improve eyesight, but nothing more specific than simply experimenting with multiple lenses can be associated with how he invented the compound microscope. It is worth noting that at the same time experimentation by other spectacle makers and lens makers was leading to the discovery of the telescope, another optical instrument of two lenses. Two decades later, Galileo Galilei built a compound microscope and changed the lens design lens (convex and concave lens).
Galileo didn't invent anything he just helped improve the telescope.
The diaphragm reduces the light from under the stage which can improve the image contrast.

You would use the diaphragm and fine-adjustment knob.
galileo galilie improved the telescope
Gallilio improved the telescope in 1609, one year after it was invented
Galileo Galilee
electron microscope.
pooo
nope...
Image is everything.
yes it did !!!
The reflecting telescope
Focus the lens.
Get a bigger telescope. Resolution is proportional to the size of the telescope. But due to the atmosphere, there is a practical limit beyond which it makes no difference what the telescope size is.
You could make the telescope able to see better in the dark and make it more portable.
