20 Most Recent Edu-Science (10166) Telescope - Page 4 Questions & Answers

Here's a link on how to build your own telescope. The lens type and configuration determines how far you can see and how clearly.

Can you focus on a distant object during the day time? Do you still have the "diagonal" if this is a refractor style telescope? This is a diagonal it goes into the focuser and then the eyepieces go into the diagonal. Put the eyepiece with the largest number written on it into the diagonal and practice focusing during the day time. DO NOT USE the 2x barlow if you have one.

Many people have the same problem-- with these small telescopes you are stuck with seeing only the moon, and several other planets, and maybe a few bright star clusters.

These are all TINY objects (except for the moon).... when you look through the telescope you are looking at a section of sky about the size of your fingertip held at arms length-- the scope must be pointed DIRECTLY at the object. Practice on the moon first-- and then try to find Saturn which is up in the sky right now-- it looks like a dim (slightly yellow) star.

Contact Toys R US that sell this telescope-- or use either www.stellarium to control the scope.

The disk is not actually needed it is just a planetarium software like Stellarium. All the goto controls are inside the hand controller.

You will need to experiment replacing the lens in various configurations to see what works.

Next time NEVER disassemble an eyepiece or a telescope lens. Only the outside surfaces ever need cleaning.

Look at this picture:

The secondary is mounted toward the front of the telescope tube underneath the focuser (hole).

The scope must be collimated once you install it.

Telescopes generally will display images upside-down, due to the way the image is magnified. On many telescopes, the eyepiece is removable, and can be exchanged with many different attachments and lenses. One of which being an image rectifier (or image flipper), which flips the image back to normal. Unfortunately these lenses can be pretty expensive, and will reduce the amount of light being passed through the telescope due to the addition of more lenses, so are only primarily used for day terrestrial viewing. Hope this helps.

Stars always look like--- just a star! They are too far away to see a disk.

The moon should be your first target with that scope. Also the Orion Nebula, which is the center "star" in Orion's sword. It looks loke a star without a telescope; but it's many stars and a nebula cloud WITH a telescope.

Go and buy the book "Nightwatch".

You cannot -- parts are not available for this small imported telescope. You might be able to find a regular photo camera tripod that would work.

The 4 mm is VERY difficult to see through-- use the eyepiece with the largest number written on it and NOT the 4mm.

They do not have one. This scope is being sold by Toys R Us. No web site.

You must use the eyepieces--

It isn't a problem. Astronomical telescopes usually show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear.

It is possible to fit an erecting prism or eyepiece to most astronomical telescopes, and some of them come with one (your main scope may have one), but one wouldn't bother to do this with the small finder scope.

Planets travel across the sky on the same "path" that the sun took during the day. This is called the ecliptic (path of the sun.

Jupiter is up after dark and is VERY bright -- point the telescope to the BRIGHTEST "star " in the sky after dark.

Sorry the manual cannot be found on the internet. Read my TIPS on my profile page, and contact Toys R Us they sell this scope.

These are sold by Toys R Us -- go by a store and see if you can copy a manual. There are none available on the internet.

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.

Any photo tripod would work if you can attach the tube. Toys R us do not provide any instruction manual, and they do not sell parts.

We receive the most complaints on this brand. It is really a TOY telescope. Sorry.
