No, they just use a digital camera and "drive" the telescope from a computer, looking at the image on a computer monitor. Often they are thousands of miles from the telescope; it is all done by remote control.
It's time for a 2 inch eyepiece and i'm stuck between two.
The 30 mm GSO Super-Wide
Or the 32 mm Q70 from Orion.
Which would u prefer?
They are actually made by the same company. GSO is Guan Sheng Optical of Taiwan, one of the largest manufactures of optical devices in the world. They contract out to anyone who wants their services.

For a modest fee and a certain minimum purchase quantity, you can even have them personalize the eyepiece instead of theirs or Orion's. A buddy of mine did that for our astronomy club.
Optical Telescope Does the International space station have an optical telescope onboard?
Does the International space station have an optical telescope onboard
Probably, though I am not sure. You do know they also have the Hubble satellite telescope, which would probably be better than anything on the station anyway.
Geoff--I never said the Hubble was on the ISS. I said the Hubble was better than anything on the station.

What type of optical telescope is most commonly used for large research telescopes? why?
plz help!!!! ; )
Your teacher is probably looking for the word "reflector" here because of the size of the objective mirror. A true refractor lens can only be so big before it is no longer practical due to the length of the Optical tube assembly.
Could the worlds most powerful optical telescope see the items that we left on the moon?
Such as the bases of the lunar modules, lunar rover etc.
No, no existing telescope can provide enough angular resolution. The Moon is just too far and those objects are just too small. The Hubble Telescope, one of the best telescopes we have, can only see things as large as a stadium on the Moon.
Lunar landing modules, some equipment and even foot tracks left by the astronauts have been photographed by the Lunar Reconnaissance Orbiter, which is basically a satellite orbiting the Moon.
optical telescopes Would aliens in other galaxies develop optical and radio telescopes to explore the universe?
Possibly, it would depend a lot on how they view the environment around them. For instance, it would make no sense for them to build a telescope that sees visible light, if they can only see in ultraviolet. Or, it might not be wise for them to build devices that emit radio waves on purpose if they happen to be severely damaged or injured by radio waves.
An alien civilization may build mainly ultraviolet or infrared telescopes if that's how they happen to view their environment. They might use microwaves to communicate electronically instead of radio waves so they might build a microwave telescope of some kind. It is important not to assume that any advanced alien species must observe or interact with their environment the same as we do. That would be an incredibly short-sighted assumption.
We have creatures here on Earth that are able to use electromagnetic fields to navigate, such as birds. We have creatures on Earth that must breathe air, yet they live in the water instead. On some planets there might exist a species that is opposite. Perhaps they live on land but breathe water. On Earth we have creatures under the sea that breathe gold believe it or not.
We have discovered some of the most exotic forms of life on Earth living off volcanic vents under extreme pressures that would be instantly toxic to us. It is entirely within the realm of plausibility that life could arise on a planet with much the same conditions that exist near the undersea volcanic vents on Earth. Who knows how far life like that could evolve in those conditions, especially if those conditions are optimum for that species.
Imagine a planet orbiting a star that is 12 billion years old (about 7 or 8 billion years older than our sun). Say the planet has an atmosphere of almost entirely carbon dioxide with methane oceans and heavy volcanic activity. Say the planet also has a mass 10 times that of Earth and a high gravity to match. Throw in some sulfuric nitro-methane clouds and matching precipitation, and an appropriately hostile surface temperature to make this scenario work for the most part planet wide. Could life exist there? Of course it could. We know this because we have life on this planet right now that lives in environments even harsher than that.
In fact, exotic life of the variety that could survive these harsh environments may be more common than the carbon based "mammalian","reptilian", "avian" or "insectoid" forms of life that we are so accustomed to here. As clearly there are many more "hostile" type planets that are uninhabitable to us than there are "Earth-like" varieties.
To boot, many of these types of aliens that might survive on planets such as the one in my example, might find a planet like Earth as hostile to them as their planet would be to us. They may find our planet in their telescopes, take a few readings, and move right on to the next one after deeming our planet a lifeless ball of mostly toxic liquid. I try my best not to make any assumptions of what aliens might be like since there are literally uncountable possibilities. We might look directly at the surface of a planet that harbors a civilization thousands of years more advanced and pass right over it because we don't know what we are even looking at.
When discussing the possibilities of what alien life might look like, or how they might behave or interact with their environment, it would be wisest to keep your mind as wide open as plausibility might allow.
Explain why optical telescopes in orbit are able to receive better information than ground-based telescopes.?
like about telescopes in sky
Two main reasons. Firstly, being above the atmosphere it avoids the problems of turbulent air, pollution and cloud, resulting in much better definition and resolution. Secondly, they avoid the inherent limitation of ground based telescopes that everything in the sky eventually sets below the horizon, thus limiting the time you can spend looking at it. The Hubble telescope can be pointed at one area of space for hours or even days, which is how images such as the Ultra Deep Field were collected. The objects in that image are so faint that many days of exposure was required to produce the image.
