How does a camera lense work different from a telescope?
Question by water_skipper: How does a camera lense work different from a telescope?
How does a telescope work different from a camera lense? I’m specifically wondering about magnification. With a camera lense, a longer lense means higher magnification so to get really high magnification it needs a really long lense. With a telescope they just change the eyepiece to get higher magnification and don’t change the length of the telescope.. How is it telescopes can change magnification like that and camera lenses can’t? I asked this question under physics already and didn’t get any decent answers.

Answer by mike1942f
In a telescope where you can change the magnification it is a reflecting telescope and the eyepiece goes in the side. What you are actually doing is using a small telescope to look at a small part of the captured image and enlarge it for your eye – you are not changing the light capturing ability or enlargement of the over all telescope.
In a refracting telescope with the viewing on the end through lenses, you are using lenses the same way the camera does – adjusting the focal length and viewing the result.

Galileo’s Glassworks: The Telescope and the Mirror
Galileo’s Glassworks: The Telescope and the Mirror
The Dutch telescope and the Italian scientist Galileo have long enjoyed a durable connection in the popular mind–so much so that it seems this simple glass instrument transformed a rather modest middle-aged scholar into the bold icon of the Copernican Revolution. And yet the extraordinary speed with which the telescope changed the course of Galileo’s life and early modern astronomy obscures the astronomer’s own curiously delayed encounter with the instrument. This book considers the lapse between the telescope’s creation in The Hague in 1608 and Galileo’s alleged acquaintance with such news ten months later. In an inquiry into scientific and cultural history, Eileen Reeves explores two fundamental questions of intellectual accountability: what did Galileo know of the invention of the telescope, and when did he know it?
The record suggests that Galileo, like several of his peers, initially misunderstood the basic design of the telescope. In seeking to explain the gap between the telescope’s emergence and the alleged date of the astronomer’s acquaintance with it, Reeves explores how and why information about the telescope was transmitted, suppressed, or misconstrued in the process. Her revised version of events, rejecting the usual explanations of silence and idleness, is a revealing account of the role that misprision, error, and preconception play in the advancement of science.
Along the way, Reeves offers a revised chronology of Galileo’s life in a critical period and, more generally, shows how documents typically outside the scope of early modern natural philosophy–medieval romances, travel literature, and idle speculations–relate to two crucial events in the history of science.

what is a good telescope for a serious amateur astronomer?
Question by ABC123: what is a good telescope for a serious amateur astronomer?
I have a big interest in astronomy and already own a reflecting telescope but its old, porr quality and peices are missing. So what is a good telescope that I could buy?? I want to view planets and deep sky objects, which would make me thing of a cassegrain, but most suggest a reflecotr.

There is no best telescope because of the fact that each person has there own opinions on them and what thy want to use them for.
If you want to view dso’s I suggest a reflector with at the minimum of a 6″ aperture(remember more aperture more light gathering)I have two Orion reflectors, 6″ and 10″ and I am very happy with both.

We are not rich, can we find a good inexpensive telescope?
Can you build a good homemade telescope?

Answer by AstroGeek
Well, although it’s probably designed for kids, you could try out the ‘GalileoScope’ at https://www.galileoscope.org/gs/ I believe the cost on that is under . It’s got plastic optics, but it’s designed to be a decent scope.
If there’s further interest you can invest in a good pair of binoculars as the next step, or save up for a decent 6-10 inch dobsonian reflector (0-500 depending on size and features)
Yes, you can build a decent homemade telescope, but if you want the cheapest route, you’re going to have to grind your own mirror. If you wish to test the astronomical mettle of your teen, I suppose that would be a good way. 
You might try one of the various ‘getting started’ guides on the net (including mine below
