One of the most surprising discoveries first-time telescope owners will find is that images may appear upside-down or backwards depending on the type of telescope. The first thought is the telescope is broken - when in fact it is working perfectly normal. Depending on the type of telescope images may appear correct, upside-down, rotated, or inverted from left to right.
Why is this? Why would I want to see everything incorrectly? For astronomical viewing, it is not important whether an object is shown correctly. In space there is no up or down. Besides, Saturn is not something you see everyday and you would not know if it was upside-down or not. A Tree, Building, Person or an Automobile for example would be important to see correctly. When you view an automobile upside-down, you recognize that this is not correct. Lets talk about the different types of telescopes and how the orientation of the image is observed through them and what you can do to correct it for land use.
Refractor and Cassegrain telescopes will produce an image that is upside down when used without a diagonal. When a diagonal is used the image will be corrected right side up, but backwards from left to right. It will look like trying to read a sign in a mirror. There are special diagonals called Erect Image Prism diagonals that can correct the backwards image for land use.
Newtonian Reflectors will produce an image that is upside down and are not recommended for land use. There are no ways to correct this with a Newtonian Reflector.
Normally the image appears upside down in the eyepiece. The reason is that to correct the image generally reduces the image quality through loss of light, and secondly, the image orientation for astronomical objects is largely irrelevant.
convex lenses for the upside down image or picture
It is not matter that the image produced by a telescope is inverted because we are watching sky objects.
optics on a telescope are upside down because lens forms a real and inverted image and even if the image is inverted , the resultant image remains the same.
no.
The most common type of reflecting telescope produces an inverted image. However, it's possible for a reflecting telescope to produce an upright image, depending on exactly how the optics are arranged.
The interpretation of the image as erect by the eye is due to the brain's ability to process visual information. The brain has learned to associate specific visual cues with upright objects, allowing it to perceive the image as erect even if the image produced on the retina is inverted. This is known as visual perception and is a result of the brain's processing and interpretation of visual stimuli.
Whenever a real image is formed by a real object,the image is always inverted. for eg when light rays from infinity falls on convex lens it forms a real and inverted image at focal plane.
The reflecting telescope
Actually, the image doesn't form in the microscope. The image forms on your retinas. The microscope focuses light in such a way that it comes together correctly on your retinas.
no you cant see image its appers in waves

retina
the images are clear and can be focused unlike a refracting telescope witch sags under its own weight causing images to be distortedAny telescope forms a real image. Otherwise, it's pretty useless as a telescope.Comments: Refracting telescopes are good these days. They should not sag. Also, Galileo's telescope formed a virtual image, and that wasn't useless.An important point about the image in a reflecting telescope is that it is inverted, as well as being a real image.
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
we do get inverted image at the ratina. But this inverted image itself is being treated as errected by our mind.
real and inverted
The cornea and lens of the eye form a real, inverted image on the retina.
The inverted or upside-down image is formed on the retina.
A telescope eyepiece usually has 2 lenses in an astronomical telescope, and it is designed to give a magnified view of the virtual image produced at the focal point of the main lens.
An image that is upside down as compared to the object are known as inverted images. Example, the first thing you will notice is that the concave side of the spoon makes your image come upside down. Such an image is called an inverted image.
Whenever a real image is formed by a real object,the image is always inverted. for eg when light rays from infinity falls on convex lens it forms a real and inverted image at focal plane.
