Meade ETX-LS Advanced Coma-Free (ACF) 6 in Telescopes w/UHTC uses advanced technologies like GPS, LNT and ECLIPS CCD imaging to do what no other consumer telescope has done before: take all the hassle out of using a tele scope. Simply flip the switch and the Meade telescopes from ETX-LS automatically aligns itself. Astronomer Inside then takes you on a guided multimedia tour of the best objects in your sky. The new aluminum mount of telescopes by Meade is lightweight and portable, yet has a rigid structure with precision worm-gear drives for the ultimate in tracking and pointing accuracy. All this combined with Meade's Advanced Coma-Free optical system provides the stargazer with the most sophisticated, yet easiest to use telescope ever.

Meade takes out all the hassles and puts in all the fun with the all-new ETX-LS telescope featuring LightSwitch technology. Now it's fast and easy to perform all start-up functions with just a flip of the switch. The revolutionary LightSwitch technology automatically delivers telescope location, time, date, orientation and alignment with the sky - all with a single touch. And thanks to Meade 's exclusive Advanced Coma-Free optics, you see it all in stunning Ritchey- Chretien-like clarity. And with the Astronomer Inside comprehensive multi-media content, you experience the universe in a way you never have before. In short, the Meade telescopes incorporate everything you've come to expect from Meade, the undisputed leader in innovation and quality.

Meade 's patented automatic self-alignment system - just one touch and it does all of the work for you. No stars to center. No bearings to take. No time or location to enter. Just flip the switch, and the Integrated Sensor Module in combination with the ECLIPS(Electronically Controlled Locate Identify Position System) CCD imager delivers all the information necessary to automatically align your Meade telescope for fast, accurate, hassle-free viewing. All at the flip of a switch.

Product Description

Product Info for Sky Watcher 18in Stargate Truss-Tube GoTo Dobsonian Telescope

The sturdy giant is reasonably light (110Lb) despite its dimensions, and being easily assembled (30-minute setup time), the whole scope boasts remarkable transportability. If you have the appetite for exceptional planetary and deep space observation, then don't miss out on this high-quality Newtonian system.

PARABOLIC PRIMARY MIRRORS

Features High-Quality Parabolic Primary Mirrors to eliminate spherical aberrations inherent in 'fast' focal length reflectors with spherical primary mirrors. The mirrors are parabolized to bring all the light rays to the same focal point to give sharp, contrasty images, which are full of detail.

SKY-WATCHER DELUXE MIRROR COATINGS

Most reflectors today usually have a coat of aluminum as the mirror surface and then an overcoat of silicon monoxide or silicon dioxide to protect it. Silicon dioxide produces a much more durable coat than silicon monoxide but requires specialized equipment to apply it and is, therefore, more expensive. Protection is needed, because, in most reflectors, the mirror is open to the elements and deterioration of the reflective layer reduces the resolution of the telescope. ALL Sky-Watcher reflectors are Multi-Coated with Silicon Dioxide as a standard for Optimum Durability and Long Term Performance.

Celestron C6-A-Xlt Optical Tube Assembly Ota Telescope W/ Starbright Xlt Coatings For Cg-5 Mount Save 43% Brand Celestron.

Product Description

Product Info for Celestron C6-A-XLT Optical Tube Assembly OTA Telescope w/ StarBright XLT Coatings for CG-5 Mount

Celestron C6A is 6.0"/150mm Aluminum Schmidt-Cassegrain Telescope Optical Tube Assembly. The Celestron C6-A XLT OTA Telescope has a 16" long aluminum optical tube that weighs only 10 lbs., making it easy to transport. CelestronC6A Telescope features a 6" aperture, a 1500 mm focal length, and a focal ratio of f/10. StarBright XLT coatings are standard for Celestron C6-A. These include high reflectivity 5-layer enhanced aluminum mirror coatings, plus magnesium fluoride antireflection coatings on both sides of the Schmidt corrector lens. These telescopes feature multicoatings that visibly increase contrast on subtle lunar, planetary, and nebula details when compared with a scope with standard coatings. They also give you higher light transmission for brighter deep space images and shorter exposure times during photography. The C-6A 's optics are hand-figured. Hand figuring the optical system is a complex optical procedure done on a commercial basis only by Celestron.

Celestron C-6-A Telescopes come with a 6 x 30mm straight-through achromatic finderscope and mounting bracket. Also standard equipment for Celestron Telescopes is a removable 1.25" visual back that holds visual accessories such as a star diagonal, tele-extender, etc. A 1.25" prism type star diagonal is also standard, as is a 1.25" 25mm Plössl eyepiece. C6-A Telescopes are equipped with a dovetail slide bar for mounting on a Celestron CG 5 or CG5 Computerized German equatorial mount. Optional split mounting rings are also available to put the tube on another mount of the buyer's choosing. Dust covers for the optics complete the supplied accessories for this OTA telescope.

With StarBright XLT Optical System design you'll see the light. One of the most important factors in the evaluation of a Schmidt-Cassegrain telescope 's optical system performance is its transmission - the percentage of incoming light that reaches the focal plane. The design of the XLT System accomplishes two crucial objectives: Develop a coating system that is optimized for visual use and for CCD/Photographic imaging.
