Here are some more information for Set Telescope:

While watching tv, you may have seen all those interesting pictures from space provided by NASA. This may have created an interest in yourself as well as in your children. This interest just might have a sparked a desire to see the stars on a more regular basis. In order to do this you are going to need a telescope.

There are a ton of places to get telescopes. Department stores, specialty shops and online at places such as amazon.com or other internet retailers. When you at the point of being ready to purchase a telescope, you need to know some things.

Just about everyone will go to a department store or toy store to find a telescope to use for themselves or their child. Yes, we all say it is for our kids, but we want to look to. You really should check out a store that has more than 1 or 2 models. This way you can get the model that will satisfy your needs.

You now have your eye to the sky. It is set up on its tripod. You focus in on a star or the moon. Your child then wants to see. He or she looks through the device and starts asking you where what you saw went. The earth moves around the sun. This makes the stars and the moon move position in the sky. You have to take into account this movement when trying to show someone what you are looking at.

All this moving around in the sky of objects may frustrate you and your child. You get what you pay for. A toy telescope just won't cut it if you are serious about seeing what is up in the heavens. You should find a place that specializes in this tube to the sky. There you will find high quality merchandise that will last. Yes, the price will increase from a telescope bought at a toy store, but that is what you are getting, a toy. A good piece of equipment will last you for many years. It might even last longer than you if it is taken care of properly.

If you are shopping online, find a telescope specialist. Do not be afraid to email them and ask questions. Tell them what you want, what you would like to get out of your star gazing experience, the area you are in and anything else you can think of.

You should also be sure to get a chart showing what is up there in the sky. It will make finding certain things easier. You don't want to waste 30 minutes looking for something, get aggravated that you can't find it and give up.

Don't waste your money on a toy telescope that will find its way to a permanent position in the closet, attic or basement. Find out what you need to know when purchasing a reflecting telescope. You can see the specific things to look for over at http://www.reflectingtelescope.net/

The Last Mission to the Hubble Telescope

The Hubble has given us pictures of merging galaxies, asteroids, new galaxies, the rings around Uranus, and other planets. It has given scientists insights into star formation and star death. The Hubble Deep Field has produced pictures of distant galaxies nearly ten billion years ago. Hubble has produced information on Black Holes and Gamma-Ray bursts, as well as other scientific mysteries of the Universe.

In fact, the news of pictures of distant space taken by the Hubble Telescope has now become a common occurrence. In fact, a recently released Hubble picture by NASA called "Clash Of Clusters" has provided new scientific evidence of the mysterious material in the Universe known as "dark matter".

"Clash Of Clusters" is just the latest Hubble success story in a remarkable record that has now spanned seventeen years. Over the years, the pictures that the Hubble Telescope has stored and transmitted to Earth have helped resolve some long standing questions in astronomy.

Hubble is also responsible for the dating of the age of the Universe at 12-14 billion years. This is a much closer date than the 10 to 20 billion year range that scientists estimated prior to the Hubble launch.

Indeed, the Hubble Telescope's contribution to our understanding of the Universe has been remarkable. That is why the last NASA mission to the Hubble Telescope is a final opportunity for NASA to revitalize the Telescope. In fact, the final servicing mission is intended to enhance Hubble's capabilities until it is replaced by its successor, the James Webb Telescope in about five years.

The NASA Mission is currently scheduled for launch on October 8, 2008. Veteran Shuttle Commander Scott Altman and astronauts Megan McArthur, Michael Good, Gregory C. Johnson, John Grunsfeld, Michael Massimino, and Andrew Feuste will use the Atlantis Orbiter for the Hubble Mission.

The astronauts will transport 23,000 pounds of hardware to the Hubble Telescope. The eleven-day shuttle mission will feature five dangerous space walks. The space walks will be necessary so that astronauts can install two new science instruments, the Cosmic Origins Spectrograph and Wide Field Camera 3 to enhance the telescope.

The Cosmic Origins Spectrograph (COS), is a new spectroscope that will study the large-scale structure of the Universe and how galaxies, stars, and planets form and evolve. The Wide Field Camera 3 (WFC3), is a new camera that will study early and distant galaxies that are currently beyond Hubble’s reach, as well as galaxies in our own cosmic neighborhood.

In addition to the new equipment, another important goal of the Mission is to repair equipment that is out of service and in need of repair. During the Mission, the ACS and STIS scientific instruments are scheduled to be repaired in place on the Hubble Telescope. The repair of the equipment will be a difficult aspect of the Servicing Mission since the equipment was not designed for complicated repairs in space.

The Hubble Telescope will also receive a new set of gyroscopes that will stabilize the telescope, and batteries and thermal blankets will be replaced to extend Hubble's operational life until at least the year 2013.

In addition, a degrading Fine Guidance Sensor unit, one of three aboard Hubble, will be replaced with a refurbished unit to help maintain the telescope's ability to point and focus on astronomical objects throughout the Universe. A successful completion of the Mission will result in the Hubble Telescope's ability to get a wider, more distant, and sharper view of objects.

NASA intends to upgrade the Hubble Telescope, so that it will have more capability than ever before. It is a servicing mission with considerable danger to the astronauts, but one that has the potential to provide science and astronomy with dramatic rewards.

It is NASA's final mission to the remarkable Telescope and the hope is that, with an enhanced Hubble, there will be more amazing pictures and discoveries of the Universe in the years immediately ahead.

what lens should I use on my telescope ?

i'm completely new to this and i'm trying to set up my telescope and i dont know which lens to ustte

That depends on several things.

What you want to look at?

What kind of telescope do you have?

What size, what focal ratio? (Do you understand those questions?)

If the telescope uses 1.25 inch eyepieces you have a lot to chose from.

If it uses .96 inch eyepieces the eyepieces available will generally be lower quality.

Some telescopes are marketed by "power". That is the magnification the telescope provides. That number can be misleading. The maximum useable power can be figured by multiplying the size of the objective (main lens) in inches by 50. If you try to use more than that, all you will see will be dark and fuzzy.

There is a lot of reading in those links.
