I need a manual for national geographic telescope model # NG70FS

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 one has a manual for that small telescope-- it's imported fropm overseas.

Here is a link to all of TASco's manuals-- find one that is similar to your telescope and use it.

No, that telescope is not worth very much and you should not spend any money upgrading it. A good tripod would cost over $100. You really cannot buy a use-able telescope for much less than $200.

Here is the one I recommend to beginners, watch this video:

I answered this question in your OTHER posting.

You won't find a manual for that small telescope --- however Meade probably has one similar to yours-- go here and download a manual for free-
