To understand this, I'll need to talk a little about how refractive telescopes work. A refractive telescope like astronomical and terrestrial uses lenses to bend light. Since stars or mountains that we want to look at a long ways away, we want to gather as much light as we can from the object and focus it all into our eye.
To do this, there is a really big lens in the front called an objective lens. The objective focuses the light down to a very small area. Now, we can think of what we're looking at as if it was in that little area that the objective focused the light to.
Here's where the different telescopes come into play. An astronomical telescope uses another, smaller lens to focus the light from the small image into our eye.
The problem with this is that the image is upside down! A terrestrial telescope has another lens to turn the upside down image right side up.
The image of a distant object as seen through an astronomical telescope is. Large astronomical telescopes always use as objective. Name the telescope, which is used by astronomers to capture the first image of Black Hole? The essential difference between an operating system like Linux and one like Windows is that. Recently, which of the following telescope of Indian Astronomical Observatory has successfully completed 20 years? Home What is the essential difference between a terrestrial telescope and an astronomical telescope.
