Collecting and Using Periodic Error Tracking Data
Follow the steps below to obtain and apply the optimal periodic error correct curve for your mount.
Step 1
Collect the Tracking Log
The first step is to obtain a
tracking log
for your Paramount. A tracking log is a record of the
position of a star’s centroid over several revolutions of the worm without making
any
tracking
corrections to the mount that can be created using the Camera Add On or CCDSoft for
Windows.
In order to successfully acquire a tracking log, you must place a star on your CCD detector and
that star must stay inside a “tracking box” for ten to fifteen minutes without making any
corrections to the mount (for several periods of the worm) so that the position of the star
during that time can be recorded.
The Paramount,
TheSkyX Professional Edition
and either the
Camera Add On
or
CCDSoft for
Windows
must configured to:
•
Turn off periodic error corrections (page 91).
•
Turn off or disable autoguiding.
•
Turn off
TPoint Add On
modeling.
•
Turn off tracking corrections from ProTrack.
