Re: PointXP Generation with Plate Solving: Where are the scripts

Alvaro Cruz-Cabrera


Thank you.  That worked well.  PlatSolve was able to find the catalog files.  Strange enough I did have the folder PlateSolve3Catalog in the same place you mentioned but none of the folders contained the catalog I downloaded from your the site your provided.  There were other folders there, but empty.

Now to make sure the code can plate solve and to automatize the picture taking.

Thanks again.

Hi Alvaro,
Platesolve3 requires the catalogs to be correct and in the correct location on your PC.  Here is the writeup on setting up Platesolve3 catalogs (from the readme file that comes with each SiTech install file.

PlateSolve3 Catalog locations!
This is important if you want to use PlateSolve3, (I highly recommend it).
PlateSolve3 (PS3), does very fast all sky plate solves (Thanks Dave Rowe!)

The Star catalog for PS3 is about 2.1 GBytes zipped up.  
You can try to download it here:
If that doesn't work, we're trying to set up a public FTP, when we get it working, we'll announce it on the list.
Anyway, you need to unzip it, and it has to be in an exact location.

In the following paragraphs, we're trying to say where the folders MUST be. On most U.S. computers,
the folders are here:
But your mileage may vary.  Sometimes it's:
C:\users\\application data,
and there's a variety of others where windows puts this folder.
You have to figure where the data files for SiTechEXE is, then going up one level.
In the following discussion, I'm going to call it:

You can find this SiTech Data folder by running SiTechExe, clicking on the Config tab,
then Click on Change Config.  Now look at the path in the top textbox labeled "Folder for SiTech.cfg"
Copy everything from the C: up to but not including the SiTechExe, then paste it into a MyComputer browser.
That's where the catalog files MUST go.

The unzipped files should go here:

When you unzip the files, sometimes it will make a folder under a folder, like this.
C:\YourProgramDataPathWhateverThatMayBe\SiTech\PlateSolve3Catalogs\PlateSolve3Catalogs   WRONG!!!
This is Wrong, and won't work

Again, the files must be here:
In the above folder, there are 3 sub folders:
