You have now completed the assembly of your Red Planet

properly aligned with the telescope in order to work properly. This alignment
is best performed during the daylight. Follow the steps below to align your
nderscopeproperly:
•PlacetheHuygenian20mmeyepiece(Fig.1-3)intothefocuser
(Fig.1-2)ofthetelescope.

Calculating Power:
Themagnicationofatelescopedependsonboththefocallengthofyour
telescope as well as the eyepiece you use. There is a simple formula you can
usetodeterminethemagnicationyouareusingatanygiventime.Simply
divide the focal length of the telescope by the focal length of the eyepiece.
For example, if you are using the 20mm eyepiece with your TP-100 telescope
the power would be:
Power = 700mm / 20mm = 35x
Usinganeyepiecewithasmallerfocallengthwillincreasethemagnication
ofyourtelescope.Itisalwaysbesttostartatthelowestmagnication
