I just purchased a Celestron 127MM reflector AstroScope telescope, for my son. He assembled the scope, put on the 39mm. eye piece on the telescope, and know he says is "all I see through the eye piece is mostly white" He is totally frustrated. What is he doing wrong? ..... Looking for something in Virginia Sky's"
Re: I just purchased a Celestron 127MM reflector...
It is NOT in focus.
Take the scope outside during the daytime and practice focusing on a distant object. Turn the focusing knob until you get a sharp image in the eyepiece.

Yes, you can, but with qualifications. You are evidently aware that you must never view the sun through the eyepiece of a scope without proper protective attachments being used. Blindness in that eye will be instant. Solar eclipse spectacles will not be sufficient protection as the light is focused powerfully at the eyepiece.
You can safely use a glass solar filter which attaches to the front of the scope. Tape it on for extra safety.
You should not ever use a solar viewing filter which attaches to the end of the eyepiece. There were a lot of these around until governments began banning them. The danger is that the concentrated heat of the solar image at that point will crack the filter, leaving your eye unprotected in an instant.
I think I already answered this question. Eyepieces are NOT assembled they are one piece like this picture: http://www.amazon.com/Celestron-93342-17MM-Plossl-Eyepiece/dp/B000YKZKNI
They simply slip into the hole of the focuser -- straight in. The larger the number written on the eyepiece the LOWER the magnification.
In the picture above there is a metal triangle holding the tripod legs apart-- it is called a "tripod spreader" or a tripod "tray"-- used for holding eyepieces and other small pieces of equipment while you are using the scope.
This scope has a ,965 in. diagonal (measure the diameter of the diagonal opening.) max power is about 120x I would get a 20mm for low power e.g. http://cgi.ebay.com/Meade-Telescope-965-20mm-Eyepiece-New-Inexpensive-/270719705992?pt=LH_DefaultDomain_0&hash=item3f0826e388
and a 9mm for higher power http://cgi.ebay.com/9MM-965-inch-Meade-telescope-eyepiece-NEW-/230597193693?pt=LH_DefaultDomain_0&hash=item35b0a9efdd
These are cheap eyepieces but it is a cheap scope. I would not put a lot of money into it.
If you get interested in astronomy, purchase a quality Celestron, Meade or Orion (for example) reflector scope.
This is a reflector style telescope. Measure the hole in the focuser-- eyepieces come in 3 sizes-- .965, 1.25, and 2 inch sizes. Buy the correct size. These are sold by many on line retailers, here is one:
Just put the eyepiece with the largest number written on it into the focuser. Take the scope outside during the day time and practice focusing on a distant object.
Meade may have the part, but I doubt it. You can call them here:

It might be easier just to replace the finder scope with one of these: http://www.telescope.com/control/celestron/celestron-accessories/celestron-firstscope-accessory-kit
or this: http://www.telescope.com/control/accessories/telescope-finder-scopes/orion-ez-finder-II-telescope-reflex-sight
Eyepieces can be purchased at many on-line retailers. Here are two:
This is a reflector style telescope. The MIRROR is in the base! Light enters the front near the focuser and goes down the tube and bounces off the mirror and back to the front and through the eyepiece. The EYEPIECE end is pointed up.
Your scope TUBE should look like the reflector telescope on this web page:
Wish you had NOT bought this telescope. For about the same price you could have bought this: http://www.telescope.com/control/product/~category_id=classicdobs/~pcategory=dobsonians/~product_id=08942
The scope above has a 6 inch mirror which is almost twice the size of the scope you bought.
The likely hood is, that the scope needs collimating. If you don't have a collimator, you can easily purchase one, online. I discovered the same problem with my scope, until I collimated it. There are many different types available, 'Red Dot' lasers, or just simply a pin hole in a eye piece fitment. The 'catseye', is the one I got. It may seem a little complicated at first, but after you have figured it all out works, it will become clear, and once you've collimated for the first time, it takes no time at all to re-collimate. There ya go, fixedYa! P.s, don't forget to give a good thumbs up thankyou :)
If this is a Newtonian reflector or a catadioptric scope (Schmidt Cassegrain or Maksutov) you may be trying to use it at too low of a magnification. Your magnification needs to be high enough that the exit pupil is less than 5 mm; to figure this divide the focal length of the eyepiece by the f-ratio of the optical tube. If this quotient is 5 mm or more the black spot you are seeing is the shadow of the secondary mirror.
