SOURCE: I have a edu science

That little scope will NEVER be able to use the 4mm with the 3xbarlow, just too mmuch magnification. The maximum possible magnification for ANY telescope is about 50 times aperture.

Your scope is about 3 inches so 150 power is the maximum.

Yes, but the ones for sale are all metal and not plastic like the ones that came with that scope (sold by Toys R Us).

They may cost more than what the entire telescope cost you.

Eyepieces come in 3 sizes --- .965 inch, 1.25 inch, and 2 inch. Measure the hole in the focuser. The .965 size is a little hard to find since most commercial telescopes use the 1.25 inch size.

SOURCE: I purchased a Edu Science 70mm Astro-Gazer

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.

The main scope is probably also designed this way, but many amateur scopes now come with an erecting prism or eyepiece attachment that turns the image upright. You may have fitted this and not realise that it is an add-on, and that it is un-natural for an astronomical scope to display upright images.

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.

SOURCE: how many times can this

The general rule is 50 times aperture. Your scope is about 2.5 inches-- so 50 times 2.5 or about 125 power--- MAXIMUM and only when the sky is very stable and transparent.

We purchased an edu science telescope. model - 70 mm astro-gazer telescope. When we look through the "finderscope" everything is upside down. What do we do to fix this problem?

DO NOT buy an Edu Science telescope. We receive many complains on these scopes.

Try this web site for a nice small Dobsonian style telescope, like this one.

I have a edu science 70mm Astro-Gazer. I lost the manual and forgot how to use it. I have 4mm and 20mm lens and I can see moon via 20mm lense. But how can I use 4mm or 3X part to magnify the view ? Thanks!

Yes, there are several telescope shops in New York that will sell you these. Like Sultan Camera. You can also buy on-line. Here are two retailers:

Can not see anything through lens but black


Try removing the dust cap at the front where the scope is.
