ACCESSORY CHART
You may need an eyepiece as sold seperately. The telescope does not come with the eyepiece as standard accessory unless you purchased a package.
VISUAL CONFIGURATION
Magnification of the Telescope When using an eyepiece with short focal length (small number in milimeters), 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.
Example: Calculating the eyepiece magnification of a telescope with 1035mm focal length.
Eyepiece| Focal length
of telescope| Focal length
of eyepiece| Magnification
---|---|---|---
PL 20mm| 1800mm| 20mm| 90x
PL 5mm| 1800mm| 5mm| 360x
PHOTOGRAPHIC CONFIGURATION
Prime focus Photography
