Astrometry.net Local Index File Location


#1

I’ve been successfully running Astrotortilla and now looking to run Astrometry.net locally via SGP. I’ve installed the local solver but it seems to be looking for the index files in a different location from AT. I’m sure there’s a way to force the local solver to look in the right directory but I can’t figure it out.

Thanks,
Don

Don,

The local solver will be looking for the index files in C:\Users\<YOUR_USERNAME>\AppData\Local\cygwin_ansvr\usr\share\astrometry\data\

The easiest thing to do is copy the files from the Astrotortilla location to there.

Thanks Andy. Another question, how then do I point AT to this location? I don’t have enough drive space to store multiple copies.

Don,

I think it can be done as follows.

  • first, you’ll need a text editor that will not corrupt the Astrotortilla astrometry.net config file by converting the line endings to DOS-style. Avoid Notepad and WordPad. Notepad++ is a good free alternative, and there are numerous others.

  • open C:\cygwin\etc\astrometry\backend.cfg in the text editor

(I’m assuming your Astrotortilla cygwin is in the default location, C:\cygwin)

  • find the line that says: add_path /usr/share/astrometry/data
    and add a line below it that says
    add_path /cygdrive/c/Users/YOUR_USERNAME/AppData/local/cygwin_ansvr/usr/share/astrometry/data

(replace YOUR_USERNAME with your Windows user name)
(the forum is splitting that into two lines, keep it as a single line in the file.)

  • Save the file. Make sure your editor does not convert the file to DOS-style line endings.
  • Run a plate solve in Astrotortilla. It should pick up the ansvr index files.

Thanks again Andy. That’s the path I was headed down and it looks like AT is properly reading the index files from the new location but I can’t get any images to solve (blind solve in seconds in SGP). These are saved images, it’s blowing 50 outside right now so no imaging. I’m not sure if I need to change any settings in AT, like the search radius? I’ve never had any luck solving saved images in AT, I’m sure I’m doing something wrong.

I am looking for the ansvr server without the full setup.
Is it still available as download?

Thanks
