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.
