What is image mosaicing?
Image mosaicing is basically turning every part of the image into smallish blocks of squares which make it look like a mosaic.
What part of a reflecting telescope would you measure to find the apeture?
The diameter of the objective mirror, or of the tube if it has one.
What part of the microscope helps adjust the brightness of an image?
The objective lens helps adjust the brightness of an image.
What part of the microscope adjust the brightness of an image?
the objective lens
What lens that magnifies the image before reaching your eye?
retina is the part in eye which inverts the image visible to us and then magnifies it.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
Are lens part of a telescope?
-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.
How is the image projected through a telescope?
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.
What is the difference between a refracting telescope and a?
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
What is the difference between refracting telescopes and reflecting telescopes?
Hi , A reflective scope uses mirrors to focus the image and the light while a refractive scope uses curved glass lenses to focus the light and the image. Generally the reflector telescope is better for deep sky viewing and the refractor is better for lunar and planetary viewing. You can also find a compound telescope which uses both glass and mirrors which is better for general viewing.

What are the parts and functions of a refracting telescope?
The most important part of a telescope is the telescope tube. Other parts are the viewfinder or optical finderscope, eyepiece, focuser, reflecting mirrors, refracting lenses, and the mount assembly.
What part of a reflecting telescope form the image?
a concave mirror and an angled plane mirror
What is part of the eye that forms an image on the retina?
these nuts
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.
Why are telescope eyepieces an important part of any visual telescope?
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
How do you columnate a schmidt-cassegrainian telescope?
There are usually 3 adjusting screws on the front of the telescope over the secondary mirror. You point the telescope at a bright star and then defocus it this forms a donut-like image in the telescope. If you center the "doughnut" in the middle of the telescope view you will see that the "doughnut" has the dark area in the middle off center (If the scope is not colminated properly). What you want to do is move the doughnut to the edge of the telescope in the direction where the dark center is "out of center". Now you will tighten one of the three screws in the front. The way to figure out which screw to adjust is by placing your finger in front of the scope where the doughnut is out of center. You will see a dark line in the doughnut image where your finger is and it will actually be pointing to one of the three screws in front - that screw needs to be tightened. You repeat these steps until when you put the dougnut in the center view of the telescope and see a perfect looking "doughnut" with the dark part centered perfectly.
What part of a camera is the iris like?
The film because it forms the real image just like the retina.
