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.

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).
