Preparing the Telescope for Collimating

Once you get the hang of collimating, you will be able to do it quickly even in the dark. For now, it is best to collimate in day- light, preferably in a brightly lit room and aimed at a white wall. It is recommended that the telescope tube be oriented hori- zontally. This will prevent any parts from the secondary mirror from falling down onto the primary mirror and causing damage if something comes loose while you are making adjustments. Place a sheet of white paper inside the optical tube directly opposite the focuser. The paper will provide a bright “back- ground” when viewing into the focuser.

Aligning the Secondary Mirror

To adjust the secondary mirror collimation, you will need a Phillips screwdriver and a 2mm hex key, or Allen wrench.

You will need to check, and adjust if necessary, four aspects of the secondary mirror’s alignment:

1.The secondary mirror’s axial position

2.The secondary mirror’s radial position

3.The secondary mirror’s rotational position

4.The secondary mirror’s tilt

The first three will probably only need to be checked and (pos- sibly) adjusted once. Thereafter, it is usually only the second- ary mirror’s tilt that will need to be adjusted occasionally.

Adjusting the Secondary Mirror’s Axial Position With the collimating cap in place, look through the hole in the cap at the secondary (diagonal) mirror. Ignore the reflections for the time being. The secondary mirror itself should be cen- tered in the focuser drawtube. If it is off-center along the axis of the telescope, i.e., positioned too far toward the front opening or toward the rear of the telescope, as it is in Figure 27b, you will have to adjust the mirror’s axial position.

To do so, use the 2mm hex key to loosen the three small align- ment set screws in the center hub of the 4-vane spider several

turns. Now, grasp the mirror holder (the cylinder that is attached to the back of the secondary mirror itself) with one hand while turning the center screw with a Phillips head screwdriver with your other hand (Figure 29). Turning the screw clockwise will move the secondary mirror toward the front opening of the optical tube, while turning the screw counter-clockwise will move the secondary mirror toward the primary mirror. When the secondary mirror is centered axially in the focuser draw- tube, rotate the secondary mirror holder until the reflection of the primary mirror is as centered in the secondary mirror as possible. It may not be perfectly centered, but that is fine for now. Then, tighten the three small alignment set screws equal- ly to secure the secondary mirror in that position.

Adjusting the Secondary Mirror’s Radial Position Like the axial position, the secondary mirror’s radial position was set at the factory and will probably not need any adjusting, or if it does, you’ll typically need to do it only once.

By “radial position” we mean the position of the secondary mir- ror along the axis perpendicular to the focuser drawtube, as shown in Figure 30. This position is changed by adjusting two of the spider vane thumb nuts, as shown. Loosen one thumb nut, then tighten the opposite one until the secondary mirror is centered radially in the drawtube. Do not loosen the thumb nuts too much, to avoid having them completely unthread from the ends of the spider vanes. Also, when making this adjust- ment, be careful not to stress the spider vanes or they could bend.

Adjusting the Secondary Mirror’s

Rotational Position

The secondary mirror should face the focuser squarely. If the mirror appears to be rotated away from the focuser, the mir- ror’s rotational position will need to be adjusted. Again, this adjustment will rarely, if ever, need to be done.

Grip the sides of the secondary mirror holder with your fingers. Then, using a Phillips screwdriver, loosen the center screw
