Aclaro que tengo ambas y de ahi el comentario.
Lo que si puedo decir es que la 75 soporta el refractor de 6" (tambien adquirido hace poco) que creo es el tubo mas largo de los que se venden en esta.
En cuanto al manual en castellano te lo agradeceria y me seria muy util.

Hola tocayo, el telescopio de la foto es el que era mio, si... era un LXD 55, el triangulo de plastico es al mero hecho de hacer de portaobjetos y de mantener las patas abiertas del tripode, es mas decorativo que funcional.
El cual si le llegas ha hacer la bandeja de aluminio mas un tornillos de varilla roscada hasta la montura, tenes uno exacto que la LXD75, por poca plata . Mira te pego una comparativa de las dos monturas, la LXD55 y la LXD 75, del cual veras que las diferencias son casi cero a nos ser por unos sellos de teflon en su interior del mecanismo.
Cual manual necesitas?? el del telescopio o el de despiece de la montura para tuneralo??
A los dos los tengo en español, tambien tengo en español el firmware para dejarlo en criollo al Autostar por si te interesa.
Bueno, abajo te pego una comparativas de las dos monturas, que en resumen, sacando los tubos de los tripodes y dos macanas mas, la diferencia en general esta en el color, del cual uno era negro (55) y la otra nueva es blanca (75) con el eje central de ajuste a la bandeja portaobjetos.
Lo que esta en rojo son las diferencias entre las dos monturas, la cual una la descarto por que se basa en un driver que no hace a la montura.
Un abrazo y espero que te ayude mas ya que vos tenes las dos monturas.

First of all a disclusure - this is all speculation based on current Data from Meade and the Meade Dealers but until we get an actual LXD75 in hand, we just won't really know.
Here are the differences and simularities from what we DO know. This is a cut and paste from the Meade flyer posted about the LXD75 - our comments are in blue and red.
Autostar Computer Controller: Includes AutoStar Suite/LPI.
-
Same LXD55,
minus the LPI Suite -
En el 2004 cuando se hace esta comparativa el CD venia sin el driver para la LPI, pero a aprtir del 2005 ya venia el cd con todos los driver de camarasOptional Ultra High Transmission Coatings: UHTC an important optional feature to optimize the performance of your Meade telescope.
-
Same as LXD55Made in the U.S.A. and Performance Tested: All Meade Schmidt-Newtonian and Schmidt-Cassegrain optics are manufactured at Meade's state-of-the-art facility in Irvine, Calif., then performance tested on an Interferometer.
-
Same, except maybe the actual manufacturing plant.Sturdy Mount with Heavy-Duty Castings: Designed by Meade's engineers and manufactured for high-performance observing and astrophotography.
-
Same mount and castings with some design changes to fit bearingsShaft & Bearing System: The sturdy German Equatorial Mount is accurate and precise. The RA and Dec axes move effortlessly on four high-precision stainless steel ball bearings.
-
Different, the LXD55 has plastic washers / bearingsHigh-Precision Worm Gears: Located on both axes for smooth tracking and slewing.
-
Same as LXD55High-Precision Pointing (HPP): For even more-precise pointing, use the HPP function. HPP puts objects in the center of the field-of-view, which allows you to confirm deep-sky objects at the faintest limits of the telescope's capability.
-
Same as LXD55 AutoStar with free firmware upgradePeriodic Error Correction: Corrects periodic errors on the RA axis over the course of one or more training periods, thereby minimizing guiding corrections during long-exposure photography.
-
Same as LXD55 AutoStar with free firmware upgrade9-Speed Drive Controls: From a rapid slew rate of 4.5°/sec. to 1x sidereal – it's all controlled from the Autostar controller.
-
Same as LXD553-Star Alignment: Ensures precise alignment while eliminating the need for a complicated optical/mechanical alignment process.
-
Same as LXD55 AutoStar with free firmware upgradeHeavy-Duty Tripod: Variable-height field tripod with spreader bar brace provides the stability and vibration damping required for visual observation and astrophotography.
-
Different tripod altogether -
en la LXD55 es de Aluminio estructural y en la LXD75 son tubos de acero de 2")Illuminated Polar Alignment Viewfinder: For quick, precise polar alignment.
-
Same as LXD55Power Supply: Powered by 8 D-size batteries. Can also be powered by optional car cigarette lighter or AC wall adapter.
-
Same as LXD55So should I buy an LXD75, or just keep my LXD55 and what about those refurbished mounts I keep seeing?
We know Meade isn't going to manufacture anymore LXD55 scopes, for sure. They are currently liquidating what they have on Ebay and to Dealers across the US in a very nobile way of saying "fair ridence" in our opinion. They are listed on Ebay for $242 including shipping which is quite a deal for such a decent mount.
Granted the LXD55 was riddled with problems, but they are easily addressed during a HyperTune or similiar tuneup, and with the addition of the new Teflon bearings from LXD55.com - it's essentially the same mount.
The two major differences are the tripod and the bearings. Is this worth $300 or more to you? Depends on the presumed performance of the bearing and tripod.
Only time will really tell. It's hard to determine just what will come of the new LXD75 (aka LXD55 upgraded mount). These are just some basic similarities and differences to think about.
