    FocusStar can be used with one or
 many telescopes.  And it can be used
 with CCD or DSLR cameras
 connected to a telescope.  FocusStar 
 is compatible with Cercis Astro
 DslrStar.  Both FocusStar and
 DslrStar may be used with computer
 or in standalone mode.

    It is self-contained; no additional
 remote control or push-button
 devices  are necessary.

    FocusStar can focus either from a
 remote location using compuer
 commands - or in the observatory
 using up/down keys while looking
 through eyepiece or selecting from
 your 9 presets.
FocusStar Main Dialog: 
Enables user to move to stored presets, manage temperature compensation, and initiate temperature management.  Temperature sensing can compensate for focus shifts - particularly in Schmidt-Cassegrain telescopes - due to ambient temperature changes.  When external temperature sensor is connected, FocusStar records temperature characteristics in non-volatile memory.
