Meade 5" LXD75 AR-5 Achromatic Refracting Telescope
Meade 5" LXD75 AR-5 Achromatic Refracting Telescope provide a new level of sophistication and precision at a moderate price. A revelation of advanced electronic and software design, the exclusive patented Meade Autostar system, included as standard equipment for Meade 5" LXD55 AR-5 Achromatic Refracting Telescope, such advantage permits an amazing range of capabilities never before offered on telescopes in this price and aperture class. Meade 5" LXD55 AR-5 Achromatic Refracting Telescope comes with objective lenses that resolve to the theoretical limits for their apertures, Meade 5" LXD55 refractors present all of the diffraction-limited optical performance obtainable from the classical 2-element achromat design. Deep-space images, in particular, are rich in resolution and contrast, with a minimum of chromatic aberration.
