Meade Zero Image-Shift Microfocuser Operating Instructions

Meade Zero Image-Shift Microfocuser
For use with LS, LX85, LX200, LX600 and LX850 Telescopes
Introduction
The Meade Zero Image-Shift Microfocuser allows precise, vibration-free image focus during visual,
CCD, and astrophotograhic applications. It also allows you to achieve focus without causing a viewed
object to move out of position in the field of view.
The microfocuser maintains precise image centering on even the smallest CCD chips. The microfocuser
operates at four speeds: Fine to fast.
To Attach the Microfocuser to the Telescope
1. Remove the dust cap from the rear cell port of your telescope. Thread the microfocuser adapter
(B, Fig. 1) onto the rear cell port thread (A, Fig. 1). Slide the microfocuser (C, Fig. 1) over the
microfocuser adapter and tighten the three set screws (K, Fig. 1) using the provided hex key.
2a. 1.25" Diagonal Prism Users: Slide the 1.25" adapter (D, Fig. 1) into the microfocuser. Line up the
thumbscrew (H, Fig. 1) into the groove in the microfocuser (Fig. 2a and 2b). Tighten the
microfocuser thumbscrews (I, Fig. 1) to a firm feel only. Slide the 1.25" diagonal prism into the
adapter (D, Fig. 1). Tighten the accessory adapter thumbscrew to a firm feel only.
2b. SC Optional Accessory Users: If using any of the Meade Schmidt-Cassegrain optional accessories,
slide the supplied SC accessory adapter (L, Fig. 1) into the microfocuser. Line up the groove on the
side of the adapter with either of the microfocuser thumbscrews (Fig. 3a and 3b) and tighten the
thumbscrew to a firm feel only. Attach the optional accessory into the accessory adapter.
2c. 2.0" Diagonal Mirror Users: Slide the 2.0" diagonal mirror directly into the microfocuser. The
adapters are not required. Tighten the thumbscrews (I, Fig. 1) to a firm feel only.
3. Plug in the Microfocuser: Plug the coiled cord attached to the microfocuser into the Focus port
located on the Computer Control Panel.
