Introducing CodeTalker - a star chart generator that talks to an ephemeris service, like JPL Horizons, and star catalogs, like GAIA DR3.
I created this software so I can get data right from JPL Horizons and plot it against GAIA DR3 stars. Faint moons are hard to get right with software alone, and fasteroids (an asteroid that moves more than a few arcseconds per minute) move very fast against the sky. I wanted something that could do both, creating a star chart that goes as deep as I need it to, with the position of the target based on my Latitude, Longitude, and Elevation. For fasteroids in particular, I also really needed an "Update" button, so I can follow the thing between the time I get oriented in the field, and when I spot it, and every so often thereafter.
I can also export plots for later use, but I much prefer to use it at the scope. Here is an example for 2005 EK70, moving at about 11"/min at present:
This object will get below 13th magnitude in a few days, so it will be fun to follow over the next few days.
For my particular telescope, eyepiece, and mount type (a dob), I have the program generate the proper field of view, and set the proper flips and rotation angle to match my eyepiece view. It has helped a lot at the scope, and I offer for your use and modification, subject to GNU GPL v3.0.
There is a manual along with it, with an initial walk through to help get your bearings.
Here is a link to the installer and the manual for the latest version: https://drive.google...x1UJFBsITQFFXFE
As the program updates, so will the installer, and if necessary, so will the manual.
