44 MAINTENANCE LX200GPS telescopes are precision optical instruments designed to yield a lifetime of rewarding applications. Given the care and respect due any precision instrument, your LX200GPS will rarely , if ever , require factory servicing. Maintenance guidelines include: a.
With the star or hot spot centered, de-focus the image. Y ou will notice that the out of focus star image looks like a ring of light surrounding a dark central spot; the dark cen- tral spot is in fact the shadow of the secondary mirror . T urn the focus knob until the ring of light fills about 10% of the eyepiece field-diameter .
46 i. As a final check of alignment, examine the star image in focus with the higher power eyepiece as suggested (j), under good viewing conditions. The star point should appear as a small central dot (commonly referred to as an “ Airy disc ” ) with a diffraction ring surrounding it.
