The 8" LXD75™ Schmidt-Newtonian telescopes with their large-aperture and fast f/45 optical systems provide spectacular wide-field images for the discriminating deep-sky observer and astrophotographer. Utilizing Meade’s Schmidt-Newtonian optical design, this telescope with optional UHTC™ coated optical package eliminates distracting diffraction spikes and coma found in star images common to traditional competitive Newtonian reflector designs. This high-precision, individually figured 8" Schmidt-Newtonian telescope rides effortlessly on the new AutoStar®- controlled LXD75™ equatorial mount and tripod—setting a new standard in its class for mechanical strength and smoothness.
-Premium Meade® LXD75 Schmidt-Newtonian optics including a Pyrex® primary mirror for exceptional thermal stability.
-Individually figured optics, and fast f/ratios for a superior wide field optical system renowned for its exquisite smoothness, performance and short exposure times.
-Ultra-High Transmission Coating (UHTC™) provide 15% more light transmission over Meade’s standard coated optics (available upon request).
-Virtually backlash free equatorial mount incorporating heavy-duty castings and two high-precision stainless steel ball bearings in both RA and Dec axes.
-Smart Drive™ Permanent Periodic Error Correction (PPEC) corrects periodic errors on the RA axis minimizing guiding corrections during long-exposure astrophotography.
-New 3-star alignment for enhanced pointing accuracy.
-8x50 viewfinder and standard precision all-metal 1.25"/2" O.D. rack & pinion focuser.
-AutoStar Suite™ included as standard equipment. Lets even the novice
stargazer capture and process stunning images of the Moon, Saturn, Jupiter…and more.
