Power is calculated by dividing the focal length of your telescope's objective lens
(probably indicated on the focus tube) by the focal length of the eye lens you
select. The focal length of the eye lens is usually indicated on the eyepiece itself.
The longer the focal length of the eyepiece, the less the magnifying power of the
telescope; the shorter the focal length, the greater the power. So when you
select an eye lens to insert into the diagonal prism, you're really choosing what
magnifying power you wish to use for observation.
Using the digital camera module as a PC camera:
1.
Screw the objective lens unit back to the digital eyepiece module if it has
been removed for telescope viewing. Care should be taken not to make
fingerprints or dust on the lens and the sensor of the camera.
2.
Place the camera unit on the stand as shown below.
Figure 6
3.
Connect the camera module to the USB port of the computer
- 9 -
4.
Start “PhotoImpression” or other Imaging applications from the Windows
Start menu.
5.
Adjust the focus by rotating the lens until a clear image is displayed.
6.
You can take still pictures and save them in the computer using the same
procedure as described in the section “Using the Telescope in Digital Mode”.
7.
To use the camera module as a web camera for video conference, you need
to install applications like “Netmeeting” or “MSN Messenger”, which can be
downloaded from Microsoft’s web site. Please refer to the corresponding
application manual.
Handling note:
The image sensor inside the digital eyepiece is a delicate integrated circuit and
must be handled carefully. When you remove the lens from the camera, dust may
fall on the sensor. Only use a blower to clean the dust. Never touch the sensor.
