Starlight Xpress CoStar |
|
CMOS (Stand-alone) Autoguider |
|
|
 |
 |
|
The CoStar is the latest miniature Autoguider from those
innovative guys at Starlight Xpress. Only 45g (1.5oz), this
is the lightest dedicated autoguider on the market but
believe me it can really punch well above its weight and all
in a package no bigger than your thumb. Too good to be true?
Not anymore! |

Big things can come in small
packages and the CoStar from Starlight Xpress really is no
exception. |
