0.9m Telescope Specifications and Capabilities


_______________________________________________________________________________

   The following information is based on observations taken at the CTIO 0.9m 
     during the RECONS astrometry/photometry program that has been running 
                                 since 1999.

    These are meant as guidelines --- you may do better or worse for your
       specific program, depending on how you design your observations.
