Sign off on the laser pointer optical axis adjustment

Check whether the optical axis of the laser pointer coincides with the optical axis of the telescope by carrying out the following steps.

1) On the center of a piece of graph paper or white paper, draw a target in the form of a vertical line and an intersecting horizontal line.

2) Set up the target about 10 meters from the IS, and collimate the instrument to the point of intersection of the two lines.

3) Turn on power to the instrument, press the star key mode, and then press the L. P. key, lighting up the laser pointer.

Checking of laser pointer's optical axis 4) With the instrument collimated to the point of intersection of the two lines, check whether the center of the laser pointer is within about 6 mm of the point of intersection.

5) If the center of the laser pointer is within about 6 mm of the point of intersection, there will be no problems with using the instrument.

If the distance is greater than 6 mm, carry out the following steps to align the center of the laser pointer with the point of intersection, and to align the laser pointer's optical axis with that of the telescope.;
