Galilean Telescope

This is a working composite of Galileo's two known original telescopes at the [Museo Galileo](https://www.museogalileo.it/it/) in Florence.

- 2427 - w/ 51mm objective w/1273mm fl, 25mm eyepiece w/ -94mm fl - ~14x magnification
- 2428 - w/ 37mm objective w/980mm fl, 22mm eyepiece w/ -47.5mm fl -. ~20x magnification

The goal is to create an easily 3D printed "Galilean" telescope, faithful to Galileo's work without being a museum replica, with improvements to allow it to easily use modern telescope mounts, compare performance to Kepler's optical improvements as well as modern telescopes and allow extensions to use cameras and Galileo's heliograph method of observing the Sun.

It uses a 50.8mm 1000mm focal length planoconvex objective and a 25.4mm -50mm fl planoconcave eyepiece. This is a mixture of the original Galilean telescopes - preserving the light gathering power of the 50mm objective with the greater magnification of the later, more compact telescope.
