Now you can obtain the most precise image focus possible — truly to a microscopic level — during visual and astrophotographic applications, and, during CCD applications, simultaneously maintain precise image centration on even the smallest CCD chips. Included as standard equipment on all LX200GPS Schmidt-Cassegrain models, the Meade Zero Image-Shift Microfocuser operates at 4 speeds from extremely slow to fast; the entire microfocusing operation is actuated through the Autostar II handbox and powered from the telescope"s control panel. Coarse manual focusing is effected through the telescope"s manual focus knob.
