Go to Meade's web site and download one of the REFRACTOR manuals that is similar to your telescope. They all go together about the same way.

Manufacturer is unknown for this scope, but it probably originates in China and is resold with the National Geographic brand name, 150$ seems a little high for a used one. I would probably price it at 100-125$ depending on the condition and the included accessories, if any.

You will not find a manual for that imported telescope. NEVER buy scopes from Ebay, craigslist, or any of the big box stores unless you know what you are buying.

Most of them are imported and have NO CUSTOMER SUPPORT!

Do NOT attempt to look at the Sun through a solar filter! These can crack from the heat and you will be blinded instantly.

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 National Geographic, 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.

I need a Manual for National Geographic NG114AZ as well as replace the adjuster for the erecting eyepiece. where do I get these>


I think you are asking for a replacement focuser. You can probably find one here: http://www.ebay.com/itm/4-5-or-6-Telescope-Reflector-Tube-1-25-Newtonian-Focuser-Metal-Plastic-NEW-/360936594869?hash=item54097f5db5

A manual is another question. These scopes are imported and no manuals are available. However the manual only has assembly instructions it does not tell you how to use the telescope to find objects in the night sky.

Find a local Astronomy Club and the members will help you set it up-- very easy once you see it done 1 time.

Clear skies.

No manuals are available for that small telescope. The manual would only have assembly instructions it would not tell you how to find objects in the night sky.

Locate an Astronomy club and the members will help you learn the night sky.

Everything is upside down its an inexpensive national geogra childs telescope when you look thru it everything is upside down


Yes all astronomical telescopes are upside down! No up or down in space!

You can buy an erecting diagonal for about $45 from Orion Telescopes to use for terrestrial viewing.

National Geographic NG70CA Telescope .... help with


Your small telescope will never get beyond about 100 power --- the maximum resolution is calculated as 50 times aperture under perfect conditions!

Use the eyepieces with the LARGEST numbers only and don't use the barlow.
