I have an ieq45 mount and I'm trying to set up the PEC. The questions I have may be generic to any mount but in the ieq45 manual it says the first step to record PEC is to:

"Setup the mount with a telescope in autoguiding condition by connecting a guiding camera to a computer via ST-4 autoguidng port or ASCOM protocol"

I assume that means I should actually have my scope autoguiding on a target. Is that correct?

Then the manual says to:

"Press MENU, select “Auto Guide” and press ENTER. Select a guiding speed from 0.10X to 1.00X"

That's a pretty big range of numbers for guide speed. Any idea of what value to select and why? Also what exactly does the guide speed mean/do anyway?

Thanks for any help...John

John -

Yes you need to be autoguiding. The guide speed represents the percent of calculated correction to actually send to the mount. Most use .50 but you can play with this and see how your mount responds.
