If the alignment screw is a large screw

First, using the 3mm Allen wrench, turn the large screw clock-
wise a small amount, no more than a 1/4 turn. (Figure 4a)

Now, with the 2mm Allen wrench turn the two adjacent small
screws (Figure 4b) counterclockwise no more than 1/4 turn.

Locate the small screw that is 180° opposite the first screw
(Figure 4c) and turn it clockwise no more than 1/4 turn.

Turn the two large screws adjacent to the small screw
(Figure 4d) counterclockwise no more than 1/4 turn.

Repeat the above steps until the front opening is centered in
the direction you wanted it to go. You may need to repeat this
(or the small screw adjustment process) with other screws in
order to align it in other directions.

Figure 4c:

Turn the small

screw that is 180° opposite
the first screw clockwise no
more than 1/4 turn.

Figure 4d:

Turn the two

large screws adjacent to the
small screw counterclockwise
no more than 1/4 turn.

Figure 4a:

Using the 3mm

Allen wrench, turn the large
screw clockwise a small
amount, no more than 1/4 of
a turn. (Note, actual selected
alignment screw will vary.)

Figure 4b:

Now, with the

2mm Allen wrench, turn the
two adjacent small screws
counterclockwise no more
than 1/4 turn.

If the alignment screw is a small screw

First, using the 2mm Allen wrench, turn the small screw
counterclockwise a small amount, no more than a 1/4 turn.
(Figure 5a)

Now, with the 3mm Allen wrench, turn the two adjacent large
screws (Figure 5b) clockwise no more than 1/4 turn.

Locate the large screw that is 180° opposite the first screw
(Figure 5c) and turn it counterclockwise no more than 1/4 turn.

Turn the two small screws adjacent to the large screw (Figure
5d) clockwise no more than 1/4 turn.

Repeat the above steps until the front opening is centered in
the direction you wanted it to go. You may need to repeat this
(or the large screw adjustment process) with other screws in
order to align it in other directions.

Repeat these two procedures as needed until the view
through the scope resembles Figure 2b.

Finishing Collimation

Once you have finished adjusting your telescope, you will
need to perform another star test (described earlier) to check
the collimation. If your telescope appears collimated after
star testing, it should not need adjustment again unless it is
roughly handled.

If you have gone through this process and your telescope is
still out of collimation, please contact Orion customer sup-
port.You may need to return the telescope for repair (covered
on warranty for 1 year after purchase).

Figure 5a:

Using the 2mm

Allen wrench, turn the large
screw counterclockwise a small
amount, no more than 1/4 of a
turn. (Note: Actual selected
alignment screw will vary.)

Figure 5b:

Now, with the

3mm Allen wrench turn the
two adjacent large screws
clockwise no more than
1/4 turn.

Figure 5c:

Turn the

large screw that is 180°
opposite the first screw
counterclockwise no more
than 1/4 turn.

Figure 5d:

Turn the two

large screws adjacent to the
small screw clockwise no
more than 1/4 turn.
