Eypieces in telescopes usually come in two sizes .9" and 1.25" diameter. There are hundreds of scientific companies or telescope companies that can supply you with an inexpensive replacement. The eyepiece focal lengths, usually in millimeters, determines the magnification of the telescope. The focal length of the main lens divided by the focal length of the eyepiece is the magnification of the telescope. Usually two eyepieces are enough for your scope. Good luck

We have a Vivitar 50x/100x Refractor Telescope. I can't find the eye pieces. Any ideas on where to find them online? Most of the comments/reivews I've read say it's not a good telescope anyway. Comments?


Commonly available astronomical telescope eyepieces are 1.25 inches in outside diameter. If the eyepiece tube on your scope is that dimension (inside diameter) then you will have no trouble finding lots of them in various focal lengths on Amazon or eBay. However, there are lots of "toy" telescopes that use proprietary eyepieces of smaller sizes, and these would be harder to get hold of.

Hi, a few days back I purchased Nexstar 4SE. I set it up exactly how it says in the manual still I cannot see any magnifying views from the eye piece. While aligning the telescope I can find the moon from StarPointer but when I look in the eyepiece I can't see moon. When I look at stars from the eye piece they just appear like a tiny dots (just like they appear to naked eye). I am confused what step I am missing here. Or it it possibility that the eye piece is a defected piece? Please help!! Thanks,Neha


Stars will always appear as points. It is not possible to magnify them enough to see them as disks because they are all extremely far away. A telescope will however show you stars and other objects that are too dim to see with the naked eye.You will be able to see the planets as disks, and even features on the planets, such as the bands on Jupiter, the rings of Saturn and the phases of Venus, and also moons around some planets. There are other objects that will show more detail when magnified, such as nebula. You will be able to see a lot of craters and other detail on the Moon.Your problem is simply that you are not pointing the telescope at these objects. This seems to be one of those telescopes that "automatically" finds objects, but these so called "go to" scopes only do this when they are set up properly. I can't say what step(s) you have missed, but clearly even if the scope thinks it is pointed at the moon, if you can't see the moon, it is NOT pointed there. The Moon will fill the field of view even with the least powerful eyepiece. If you are seeing stars as points, then the eyepiece is focussed and working properly.

Cant see out of 49114500 telescope


Here is a beginner's instruction on different types of telescopes--http://www.uk-telescopes.co.uk/beginners_guide%20to%20telescopes.htmYes I know the box said 650 power but that was a BIG BIG lie-- the smaller the number on the eyepiece the more magnification. Do NOT use the 2x barlow which doubles the normal eyepiece power in these small telescopes--- just way to much magnification. This is NOT necessary to view the sky at night. I almost NEVER go over 100 power in my 8 inch telescope-- once in a while maybe 175 power. Sp use the eyepiece with the largest number on it--- to practice focusing during the daytime.Try to locate a local Astronomy club and attend one of their star parties and ask questions. You can bring the telescope with you and they will help you with it.

Can't See anything with Vivitar telescope


Put the lowest power eyepiece in the telescope-- that's the one with the LARGEST number on it.Go outside and practice focusing on a distant object at least 100 yards away.... turn the focus know very slowly.

The eye piece lens is missing. How do i find the model number of the telescope to order a new eye piece and a manul for this telescope


Most telescopes use a standard fitting eyepiece with a 1.25 inch outside diameter barrel. You can measure the mount where the eyepiece goes to make sure that yours is this size, then search on eBay or Amazon for "1.25 eyepiece" and you will find many available. None of these will be made by "Edu-Science", but any make will fit.The other variable will be the focal length of the eyepiece, which is what determines it's power. The power of the scope will be the focal length of the main objective divided by the focal length of the eyepiece, so a 9mm eyepiece will give a higher magnification (and be dimmer and harder to focus and find objects) than a 20mm eyepiece. It is usual to have two or three different focal length eyepieces for viewing different objects.You will find a large variation in prices, which is partly due to the difference in quality and type of construction of the eyepieces. Kellner eyepieces are simple and cheap, whereas Possl or orthoscopic ones are more complex and cost more. There are reasons why people will pay more for the better eyepieces. Avoid eyepieces marked with the letters "H" or "SR" before the focal length.There is an excellent website for beginner telescope users at THIS LINK

Telscope eye piece


Eyepieces are for the most part interchangeable. Your scope will have a focuser on it in one of 3 diameters. 2", 1.25", and the rare .965". Most inexpensive scope will use a 1.25" eyepiece. 2" focusers are usually found on more expensive scopes used for astrophotography due to the increased field of view with the larger diameter. Plossl eyepieces are fairly inexpensive and are good for all around use. I would suggest getting 2 one at 25mm or greater and one around 9mm. http://www.telescopes.com has a large selection however their are many suppliers out there. Good luck and happy star hopping

My father received a really nice Maede telescope, model 2114 I believe, a while ago, and I decided to take it out of it's attic resting place to actually get it working. However I believe it is missing the eyepiece. I have the viewfinder but no eye piece to actually see into the telescope. where can I find a replacement piece?

We had the 20mm eye piece in and we turned the focus all the way clockwise so the eye piece was all the way in. We had the cover off, we had a very clear starry night, we live in the country, moved the scope around for 20 minutes, trying to find any star, and could not see anything...did we do something wrong? When you are looking through the star finder with the LED, so you psotion your head behind the scope barrel and try to put the star in the LED or do you 6" away or where, because as I moved my head, the site changed. By using the scope in the daylight, looking at an object and focusing it in, how does that correspond to us being able to use it at night? We are excited to use this, but are frustrated .... thanks for your help.


First find a local Astronomy club -- the members will help you.Second, you must first align the red dot finder with the main tube-- there are knobs on the side and bottom (usually) to move the red dot. Point the scope at the top of a telephone pole in the distance during the day time-- wget the top in the center of the eyepiece of the main tube. Without moving the main tube adjust the red dot so it points at the exact same spot.Turning it all the way in or out is NOT how you focus-- there is a small "spot" when the eyepiece is in focus, and every other eyepiece must be refocused. Turn the knob slowly until the star or the moon comes to sharp focus.Read my tips on my profile page. www.telescopeman.orgwww.telescopeman.uswww.telescopeman.info
