Here is the code with comments that produces the output plot that I consider a good result. AstroTortilla is a package of common astrophotography tools intended to automate basic tasks such as polar alignment. To get the plot (first image) like that using Cartopy requires some steps that are interesting to follow. So that, it is quite different from your second plot (Orthographic projection). First of all, your first image is Azimuthal Equidistant Projection. Re: Cartes du ciel or skychart If you configure both the sky chart application and SharpCap to talk to the Ascom driver for the mount then the synchronisation between the applications should work automatically both will periodically update based on any changes to the mount's position and both will be able to send commands to move the mount. The English translation for the name of this application is Sky map or Sky chart, but this apps French name, Cartes du.
