Re: Autoguiding with a Sky Model in Place?

Wayne, yes you can and should leave tracking rate correction on.

You might be able to track ISS but the computer time has to be perfect and ISS not have changed course after you acquire coordinates for it.

Ray would I still leave tracking correction on while using Horizons?

Just tried Horizons for tracking the BepiColumbo mission. Got it to work but would have to cut down a number of
trees and neighbors house!

Can you use that for ISS passes? What time units would work?

Yes, would have to as it would override the lunar/solar setting.

A better option is to use Horizons (the application included with APCC) to get the dual axis motions of the moon
or sun. Then tracking will be much more accurate than the mount's built in solar/lunar rates.
