   Hello everybody !

 

  I was very pleased to discover that Meade ACF-SC 8'' and 10'' LX200 OTAs are now on sale on the Astroshop website - the main online vendor of astronomical instruments in Europe. This is a smart and useful move since until now it was very difficult to find in Europe Meade ACF-SC OTAs except for the LX800 series.

 

  Since I am already the happy owner of a LS6 go-to telescope I am considering to also buy a Meade ACF-SC 8'' LX200 OTA. I discovered on the Astroshop website that the primary mirror of this OTA - and maybe the secondary too - is made of "borosilicate glass" . In the same time the 10'' LX200 model have both the primary and the secondary mirror made of Pyrex glass - as for my LS6.

 

   What is the difference for the visual user ? Is it a matter of thermal adaptation between the two types of glass ? A matter of durability ?  Thank you for any clarification.

I am thinking that Pyrex is more of a name for a product from Corning.  Borosilicate glass is a more generic name for the same thing or something very similar.  If there is any real difference, it would be minor.
