Hi Ned,

"...Before I purchase Guide 8 I want to be sure it works with Sidereal
Tech servo controllers. Does anyone in ths group have that experience?"

I can't say I've heard of anyone using that particular system. But
I gather it does have an ASCOM driver? If it does, and the driver has
no problems, then Guide should have no problems. (I've been very
happy with the use of ASCOM drivers. It basically means that, from
the viewpoint of Guide, all telescopes are pretty much the same. Sort
of like the way in which printer drivers mean one doesn't have to write
code for every flavor of printer on the planet. But I digress...
bottom line is, it oughta work Just Fine.)
