BRAND NEW IN BOX!!! ONLY OPENED FOR PHOTOS COST ONLY $550 SAVE $70.00 of the price of a New One
Full Warranty from Explore Scientific

The ED80 80mm f/6 Essential Apochromatic ED Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Extra-low Dispersion (ED) glass and Explore Scientific's proprietary anti-reflection EMD fully multicoated optics. This combination of glass, lenses, and coatings virtually eliminates chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition. This is a versatile optical tube assembly that can be employed as a simple grab-and-go primary telescope, as a large finderscope mounted to a larger scope such as a Dobsonian, or set up on a dual-mount rig for astrophotography/astroimaging.

A mounting cradle-ring clamps over optical tube assembly (OTA). The cradle-ring allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle. Its two-speed rack-and-pinion focuser helps make fine-focusing fast and precise. A 90° star diagonal is also included for more comfortable viewing. The mirror has dielectric coatings for a 99% light transmission for minimal light loss when using it.

Here is a Great Condition Meade LX200R 8" Telescope. Just in time for Christmas.
I have personally checked everything myself to confirm that it is in perfect working order.
This scope has the North Level Align, so all you have to do is follow the instruction for the self-alignment and your good to go.
The Optics are Clean with no Scratches or Dust. The Outside of the Tube does show minor scratches
As you can see in the photos the front cover is a bent. It still works just fine.

This is the better constructed version of the LX200 having larger fork-arms to reduce flexure and add more stability.

In this Listing you will receive ONLY the following Items:
Meade 8" LX200R (Advanced Ritchie-Chretien) Computerized Telescope
LX200 Computerized dual fork arm mount
AutoStar II GOTO System Controller (Version 4.2G)
Hand Controller Cradle
1.25" Visual Back

JW-above the clouds, and go up. ISS has taken pictures.  B-uneven electrons amounts.  BM-Calcium Carbide for lamps. TT-3 types of sprites, jellyfish, column, carrots. B-JW do not believe in Dark Matter? JW-need to test and get evidence to support postulate.  DM is a simple explanation.  TT-may be MOND.  CM-no evidence.  JW-I think we will be surprised with final answer. B-Black holes, many solar masses...missing stars?  JW-are not enough to be dark matter BM-I heard opposite, more BH than stars. TT-maybe early in universe more massive stars that collapse to BHs.  JW-graviton not found yet. but cleverly made up.
BM-neutrino can go thru a light year of lead w/ 30% chance of hitting.  JW-produced in core of Sun, detected on earth.  3 types of neutrinos. Could account for missing numbers.  B-come from all stars.  CM-2 sec early warnings of supernova due to neutrino detection.  B-neutrino travel at speed of light, solar wind comes later.

30:00.401  music: Gato Barbieri.  B-SBAU potluck June 2 for members. Chips/Dip; Mac/Cheese.  CM-outreach 6-3 REfugio, 6 tele tues....Bacara, Museum, Westmont, Lopez Lake, Carp St Beach; Asteroid Day June 31 1908 Tunguska event in Siberia.  TT-RTMC.  B-eclipse story, Aug 21  JW-Hi to daughter Laura in Port Hueneme, texted back.  BM-gravity has waves, why not a particle involved? B-spacetime continum? JW-rubber sheet not literal.  TT-spacetime, 4D? JW-time is c x T....  B-special general relativity next

38:33.971  music: McP song collection; B-banjo space music; back w/ BM on phone, card carrying members, JW-"cannot lose it" not in my spacetime.  July meeting Yair Arcavi, Aug-Karl Blasius Mars. B-monolith. Genius TV show on Einstein..how can something go thru nothing.  JW-just wrote on that in SBAU newsletter, zero in math. Can vacuum exist?  no motion in vacuum?  1644 Torrecelli made vacuum with mercury in tube.  Barometer.  B-spec/gen rrelativity? JW-special is at constant velocity, zero acceleration, e=mc2, time dilation, twin paradox. General is with acceleration taking place, elevator falling.  grav mass = inertia mass.  JW-space ships that rotate to make gravity. B-earth? JW-want to travel in straight line, feel gravity from mass.  BM-gravity sucks JW-there is no gravity the earth sucks.  B-so?  JW-expl the universe  CM-then quantum mechanics.  LHC and Fermi Lab chicago.  Texas was too expensive for a LHC during Vietnam war.  B-anti-matter in LHC?  JW-can hold in magnetic bottle.  Star Trek Enterprise amount? JW-copius amount maybe in another method. Classical vacuum take everything out.  B-anti-protons, positrons = explosion? BM-energy.

49:14.323 music: star trek tv;  B-why not more members for AU?  many listeners TT-millions on internet.  B-trojan asteroids?  CM-occulations  TT-how many looking at same occultations? CM-up to 80, but usually just a few.  B-billions of rocks?  how to nail one?  CM-100Ks know.  TT-only in belt?  CM-also near earth objects.  CM-trojans in same orbit as planet BM-lagrange point. B-Ceres, dwarf planet.  B-wrap up hour outreaches, Museum, Westmont. CM-Cachuma in July. JW-Neil Degrasse Tyson, Physics not a belief system.
