Collimating a Dobsonian telescope is relatively easy and can be done with a few simple tools. A collimator and a Phillips head screwdriver are all that is needed. To begin, the telescope should be set up and ready to observe.

The first step is to unscrew the top of the telescope primary mirror cell, normally located at the rear of the telescope. This will expose the primary mirror. Next, look down the length of the telescope tube and use the Phillips head screwdriver to adjust the three collimation screws, which are typically located at the top, bottom, and side of the primary mirror. Each collimation screw should be turned a few degrees to adjust the position of the primary mirror.

Once the collimation screws have been adjusted, the primary mirror should be collimated. To do this, the collimator should be placed at the end of the telescope tube and the primary mirror should be adjusted until the laser beam is centered. This will ensure that the primary mirror is properly collimated.

After the primary mirror is collimated, the next step is to adjust the secondary mirror. This can be done by adjusting the three collimation screws, which are typically located on the back of the secondary mirror. Again, each collimation screw should be adjusted a few degrees to adjust the position of the secondary mirror.

Once the secondary mirror is collimated, the telescope should be ready to observe. Before using the telescope, it is important to make sure that the primary and secondary mirrors are properly aligned. This can be done by looking down the length of the telescope tube and making sure that the primary and secondary mirrors are in the same plane.

Collimating a Dobsonian telescope is easy and can be done with a few simple tools. By following these steps, the telescope should be ready for observing in no time.
