That’s correct. Last night I was playing with my old laptop trying to figure out how to install Astrometry.net but it turns out to be complicated. Eventually I found about that installing Astrotorilla also installs necessary files for Cygwin and Astrometry.net. The trick about one of the installation steps is it asked you to select the range of index files. At first I let it select default index files. After this was done, then I installed ansvr and followed instructions from another SGP thread. The local Astrometry.net solving failed. So I re-installed Astrotortilla and widen the range of index files (I widened too much because it resulted almost 4GB worth of index files!!!) but that solved the problem. Astrotortilla has a PDF document describing how to do the installation and provided a formula to determine the range of index files based on FOV of your camera and focal length of your scope. It was a good instruction. The PDF document is at:
Here is an outline of how I installed it:
- Install Cygwin using default settings.
- Create “opt” sub-directory under “Cygwin” root directory. It’s needed for installing ansvr later.
- Install Astrotortilla ( http://sourceforge.net/p/astrotortilla/home/Home ). Click on the “Download” button at bottom of screen.
- Follow instructions on screen and read PDF document about choosing index files.
- Be patient about installing Astrotortilla because it can take a while depending on range of index files you selected.
- Download latest ansvr (0.14): http://forum.mainsequencesoftware.com/t/local-astrometry-net-files/143 . Scroll down and look at Andy’s very last post.
- Copy downloaded ansvr file to C;\cygwin\tmp directory.
- Following instructions from the link I provided in step #6.
In step #3, it may not be necessary to install Astrotortilla component since SGP is used for plate solving but I included it anyway and it didn’t hurt. There are several components to select including Astrotortilla, Astrometry.net, and index files. I selected all because it was a brand new install.
Hope this helps.
