[sac-forum] Re: Digital setting circle question

Steve,

NOt sure aboyut other brands, but the Sky commander has an internal clock that 
keeps track of time and adjsut the coods as the sky moves. When you put the 
scope on an EQ platform, there is an option to turn the clock off. With Sky 
Commander, there is a reset option that keps track of the motion of the 
platform. If done right, you won't have to realign the scope after a platform 
reset. I think SC is the only DSC (I could be and probably am wrong) that has 
that feature.

Hope this is what you were looking for.

Rick
