Dear Jaime,
One of ourLCD shutters will not work very well in your application. There are a few problems, and they are discussed on our web site here:
http://www.liquidcrystaltechnologies.co ... ations.htm
The biggest problem for your application is the 55% light loss going through the display in its "clear" state. If you have a very bright object in your field of view it would not be such a problem, however as we know, this is rarely the case.
We have worked with both the US Naval Observatory here in the US and also the ESO in Munich to overcome the problems of using an LCD as a shutter with no success. Sorry.
Best regards and good observing,

Tratando de ampliar la información sobre los proyectos USNO y ESA obtuve esta respuesta:
...their projects were different from yours, and also that the projects never went far enough to create any technical data. One was stopped by the 55% light loss, and the other by the light loss and also the switching speeds of the shutters (they needed a few microseconds switching and >95% transmission)
Definitivamente es un proyecto difícilmente viable con un LC-Shutter y mecánicamente complejo con un obturador mecánico...
