The main lens or mirror produces a virtual image of the obect being looked at, and it occurs at a distance behind the lens (or in front of the mirror) equal to the focal length.
The telescope also has an eyepiece whose function is to allow the oberver to see the virtual image. Many telescopes come with a range of different eyepieces that give different amounts of magnification.

∙ 13y agoA telescope is an instrument designed for the observation of remote objects by the collection of electromagnetic radiation. An optical telescope is a telescope which is used to gather and focus light mainly from the visible part of the electromagnetic spectrum for directly viewing a magnified image for making a photograph, or collecting data through electronic image sensors. A refracting or refractor telescope is a type of optical telescope that uses a lens as its objective to form an image. The objective lens of a refractor collects the distant light and brings it to a point of focus.

Why might a star in the night sky look blurry even through a telescope?
Did you ever think you had to clean the lens you look through on the telescope. If your not looking through the telescope may be you have a problem with your eye or you are glazing at the stars which can make the appearance blurry.
What telescope using lenses to make an image?
The reflecting telescope
How does a telescope form an image?
by refracting light rays that pass through it
Does a reflecting telescope produce an upright image?
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.
What type of telescope that uses only lenses to collect light to form a image?
simplest possible telescope
Can each type of image be projected on screen explain?
A virtual image cannot be projected onto a screen, because the light rays never actually to through the point where they seem to come from. A real image can be projected onto a screen, because the light rays do actually go through the point where they focus.
What is an image which can be projected onto a screen is called?
It is called a real image. Only a real image can be projected onto a screen.
When you look through a telescope why is it stated that you are looking at an image of an image?
Its because you are looking at a mirror reflection of the actual target.
How can a real image be distinguished from a virtual image and can each type of image be projected on screen?
If an image can be formed on screen it is classified as real. Virtual images cannot be projected on an image.
What uses are there for a relfecting telescope?
By using a Reflective telescope the viewer sees the image of a normal telescope, reflected on a mirror, which is viewed through a microscope, by doing this the telescope doubles it's viewing ability
The image on this is upside down at first?
retina
Is true of a real image?
a real image can be projected
What is true of a real image?
a real image can be projected
Is the image produced by a radio telescope the same as the image produced by a optical telescope?
no you cant see image its appers in waves
Why might a star in the night sky look blurry even through a telescope?
Did you ever think you had to clean the lens you look through on the telescope. If your not looking through the telescope may be you have a problem with your eye or you are glazing at the stars which can make the appearance blurry.
What IS optical spacing?
An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrumcreate a magnified image for direct view, making a photograph, or collecting data through electronic image sensors.
What telescope using lenses to make an image?
The reflecting telescope
