PHOTOGRAPHIC CONFIGURATION
Some of optional accessories shown in this chart will be needed if you take pictures with SLR camera, digital
camera or CCD video camera.
5mm
Magnification of the Telescope
When using an eyepiece with short focal length
(small number in millimeters), the image will be
dim and the range of sharp focus will be small.
The image will be harder to see so begin with an
eyepiece with long focal length.
Dividing the focal length of the telescope by the
focal length of the eyepiece gives the
magnification.
