Use with Meade De-Rotater
When using a Meade de-rotater, it is important to attach the microfocuser so that it is backed off
slightly from the de-rotater. If the microfocuser is flush against the de-rotater, the assembly will not
work properly. This is true also with other accessories that may attach flush against the de-rotater
housing.
To Attach the Microfocuser to the De-rotater
Refer to Fig. 1. Perform this assembly on a flat surface (such as a desk or a table) before you attach
the de-rotater and microfocuser to the telescope.
1.
With the de-rotater on a flat surface, thread on the adapter ring until it just touches
the housing; then back off the adapter ring (i.e., turn it counter-clockwise) one full
revolution as shown in Fig. 6.
2.
Place the microfocuser over the ring with the "hump" of the microfocuser in the 12:00
position as shown in Fig. 7.
3.
Using the provided hex key, tighten to a firm feel one of the three microfocuser set
screws against the adapter ring as shown in Fig. 8. Take care not to tighten or loosen
the adapter ring as you position and tighten the microfocuser in place.
4.
Tighten to a firm feel the other two microfocuser set screws.
5.
Attach the de-rotater to the rear cell of the telescope.
