ALIGNING THE FINDER SCOPE – Besuretoalignthefinderscopebeforeyoubegin

observing.

(1) Chooseaconspicuoustargetinthedistanceandplacethetargetin

thecenterofthefieldofviewofthetelescope.(Intheillustration,a

(2) Next,lookthroughthefinderscope.Youshouldprobablyfindthe

same target somewhere within the finder’s field of view.(The

finderscopehascrosshairs.)

(3) Aligntheopticalaxis(fieldofview)ofthefinderscopewiththe
