The Camera Adapter - National Geographic NG65FS Instructions And Owner's Manual

4) To see your subject at a higher magnification, turn the zoom ring (9) on the
eyepiece. You will have to re-adjust the focusing knob (10).
5) Note that as the zoom power increases, the brightness of the image decreases.
This is quite normal. To observe in low light situations you will find the lower
zoom powers perform better.

THE CAMERA ADAPTER

Your telescope comes with a 35mm SLR camera adapter. This allows you to attach
almost any 35mm SLR camera (a camera that uses interchangeable lenses) to the
telescope eyepiece so that photographs can be taken through the telescope – in effect
turning it into a telephoto lens.
You will need a T2 adapter ring (not included) for your particular camera brand and
model. This can be obtained at most good photo or hobby stores.
To use the camera adapter you must first remove your camera lens. You must also
remove the rubber eyecup on your telescope by gently prying upward.
Screw the camera adapter into the threaded center of your T2 adapter, as shown below.
Then attach this assembly to your camera body as if it were a lens.
