Re: Guide8 & EQMOD

Mark V Nov 9, 2010

Hey Bill & Bob,

I was able to test Guide with ASCOM and EQMOD last Saturday and am
happy to report that things went pretty well.

You were right, Bill, the time issue wasn't an issue at all. There's no
need for constant updates to time as the alignment procedure is based
on stepper location, so you could essentially take as much time as needed.
(Bob, I did use F3 to update the screen throughout the evening)

The only real consideration is location - Latitude and Longitude must
match in both Guide and EQASCOM.

Here's an image taken during a 2 hour break in the cloud cover last
Saturday. The mount was controlled via a wireless gamepad :o)

Many Thanks,
Mark V
