    Refracting Telescopes use a large objective lens as their primary light-collecting element. Meade refractors, in all models and apertures, include achromatic (2-element) objective lenses in order to reduce or virtually eliminate the false color (chromatic aberration) that results in the telescopic image when light passes through a lens.

Two-Star Alignment is identical to Easy: Align (see , above), except Autostar displays a database of EASY (TWO-STAR) ALIGN bright stars and two stars are chosen by the observer from this database for alignment. It is rec- ommended that you choose stars with which you are familiar from this database when first try- ing out this method or the One-Star Alignment method.

  • Page 29: Caring For Your Telescope, Collimation

    Collimation DS-2000 refracting telescopes are optically aligned (collimated) at the factory prior to shipment, and it is never necessary to re-collimate the optics of these models. Meade DS-2114mm and DS-2130mm reflecting telescope models are also factory-aligned, but may occasionally require re-alignment, particularly if the telescope has received rough handling in shipment.
