The Meade Schmidt-Cassegrain Optical System In the Schmidt-Cassegrain design of the Meade LX10, light enters from the right, passes through a thin lens with 2-sided aspheric correction (“correcting plate”), proceeds to a spherical primary mirror, and then to a convex secondary mirror. The convex secondary mirror multiplies the effective focal length of the primary mirror and results in a focus at the focal plane, with light passing through a central perforation in the primary mirror.

Do not point the telescope or its viewfinder at or near the Sun. Do not look through the telescope or its viewfinder as it is moving. Children should always have adult supervision while observing. Fig.1: The Meade 8"LX10 Schmidt-Cassegrain Telescope.
- 5 - INTRODUCTION The Meade 8" LX10 Schmidt-Cassegrain Telescope is a mirror- lens telescope suitable for both astronomical and terrestrial viewing. The LX10 utilizes the exact same optical tube assembly as provided with Meade 8" LX50 and 8" LX200 models and yields optical performance identical to that of these more expensive telescopes.
To assemble the telescope, follow these steps: 1. Setting Up the LX10 Field Tripod To set up the Meade LX10 Field Tripod, remove the tripod from its shipping carton and stand the tripod vertically with the tripod feet down and the tripod still fully collapsed. Grasp two of the tripod legs and, with the full weight of the tripod on the third leg, gently pull the legs apart to a fully open position.
For astronomical purposes the image orientation is of no importance whatever. For terrestrial observations, where a fully corrected image is highly desirable, the optional Meade #928 45° Erect-Image Diagonal Prism should be ordered separately. 5. Mounting the Viewfinder...

Precise polar alignment requires the use of a crosshair eyepiece — such as the Meade Illuminated Reticle Eyepiece — and a 2X Barlow lens for increased magnification (see Fig.14: Optional LX10 Electric Declination Motor.

If while turning the defocused star image flies out of the eyepiece field, then you are turning the screw the wrong way. Turn the opposite direction and bring the image back to the center of the field.
