2008年9月10日 · Constructing a Galilean refractor based on "Old Discoverer" facsimile of "Old Discoverer" Galileo learned of the telescope in the spring of 1609 from a former student, Jacques Badovere, and by late summer had fabricated a x8 telescope and by late autumn a x20 telescope.

2022年10月1日 · A Galilean Telescope you probably already have! - posted in ATM, Optics and DIY Forum: I was just thinking it would be fun to put together a Galilean telescope. I starting looking for suitable lenses and thinking about ways to mount them. Then it occurred to me that I already have everything I need, already mounted! I have a nice 4 f/10 refractor.

2024年8月28日 · A little Galilean telescope for an archery sight? - posted in ATM, Optics and DIY Forum: Hello folks, Looking for a sanity check here. If I have: PCX lens D=50mm, FL=200 PCV D=50 FL=100 space them 100mm apart Doesnt this make a Gailiean telescope with magnification 2? Does it still work if I hold it an arms length from my eye? The reason I ask is that in archery …

2004年7月17日 · 2) I wonder if there is a variation on Galilean telescope design which can offer similar increase in SB (if it does exist taht is ) but be a bit more usable. I guess anyone can use a mirror instead of a lens for objective and build a "Galilean Newtonian" wich incredible light gathering power and maybe less chromatic problems, for example.

2018年2月23日 · Galilean Telescope BY OSLO - posted in ATM, Optics and DIY Forum: Hello everyone, I am a new Oslo user and I really would like to be able to make a Galilean Telescope using this program. I have been trying a lot of times to set up a Galilean telescope but I can not make it. After doing the optimization process, the focal length changes and I am not able to …

2005年12月13日 · Galilean Telescopes - posted in ATM, Optics and DIY Forum: Hey folks,A fellow optics guy at work here mentioned that he was getting interested in making a high-quality Galilean Telescope. My first thought was, why? because what I envision is the old clunker that Galileo originally used. Single, low-quality, not well-designed convex lens, rusted tube, fancy …

2010年6月8日 · Galilean Telescope Project - posted in ATM, Optics and DIY Forum: I have a project to propose for a Galilean type telescope, perhaps like the many, many others on CN. It uses a singlet objective and a Huyghens eyepiece. Most of it involves parts from Surplus Shed and the cost is minimal.I am not an employee of the Shed nor will I profit in any way if folks on …

Galilean Telescopes: Galilean Telescope were designed by Galileo Galilee while he was using telescopes to observe the skies. Galileo used his telescopes to determine that there were rings around Saturn, as well as locating some of Jupiter's moons and seeing the surface of Earth's Moon in much greater detail.

Galilean Telescopes: While not the first to create a telescope, Galileo worked for many years, and through over 100 telescope designs, to improve the function of the telescope.

A Galilean telescope is adjusted for a relaxed eye. If the length of the telescope is 40.7 cm and the focal length of the objective is 43.9 cm, then find the power of the lenses and the magnification (a) For a diverging lens (f = - 22.0 \ cm), find the image distance for an object that is 22.0 \ …
