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

 

distant

 

tower

 

is

 

brought

 

into

 

the

 

center

 

of

 

the

 

field

 

of

 

view

 

of

 

the

 

telescope.)

 

(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

 

optical

 

axis

 

(field

 

of

 

view)

 

of

 

the

 

telescope.

  

Adjust

 

the

 

finder

 

scope

 

by

 

loosening

 

or

 

tightening

 

the

 

adjustment

 

screws

 

A

 

and

 

B(In

 

Figure

 

#4

 

Above)

 

until

 

the

 

target

 

is

 

in

 

the

 

same

 

position,

 

in

 

the

 

center

 

of

 

the

 

crosshairs.

 

(In

 

the

 

illustration,

 

the

 

top

 

of

 

the

 

tower

 

is

 

in

 

the

 

center

 

of

 

the

 

crosshairs.)
