2.If you have purchased one of the optional Viewfinders (3, Fig 1), attach it as shown using the supplied hardware. As with the focuser, a firm feel is sufficient. Overtightening may result in damage to the tube’s finish.

Your Meade Starfinder telescope was fully assembled, aligned, and tested at the Meade factory. To ensure safe shipping, the primary mirror was then removed from the telescope. Locate the primary mirror cell assembly (see Fig 1). Again, take extreme care not to touch or bump the primary mirror.

To install the primary mirror, follow these steps:

3.You will note that there is a colored marker on the rear of the telescope tube. There is a corresponding colored marker on the mirror cell. Carefully slide the mirror cell into the rear of the tube, ensuring that the two colored markers line up. Secure the cell to the tube with the hardware provided. Again, do not overtighten the screws. A firm feel is sufficient.

4.Carefully place the assembled optical tube into the previously assembled base as illustrated in Figure 1. Note that the two large bearings on the side of the tube cradle into the cutouts of the mount. Also note the orientation of the tube to the mount; the focuser should be on the opposite side from the mount’s Front Board.

C. BALANCING THE TELESCOPE

Dobsonian telescopes are designed to move easily, but at the same time remain in the position they are placed. This is achieved by carefully balancing the telescope at the Meade factory. The telescope is balanced for standard accessories.

However, should anything attached to the telescope change, for example using a larger or smaller eyepiece, using a viewfinder, or even moving the primary mirror during collimation, slight imperfections in balance may occur.

If you find that as you change eyepieces or accessories an out-of-balance condition causes annoyance, this is relatively easy to solve. Meade offers an optional counterweight set which attaches to the mirror cell using the counterweight thread. Or, with a little ingenuity, counterweights can be fashioned by the telescope owner, using fishing sinkers or washers.
