I am 99.9% certain that Starry Night does not have the capability to track a moving body (earth orbit, solar system body, etc). Some telescope mounts do have the ability to offset their tracking from sidereal for tracking moving bodies, and some software can take advantage of this feature if it is present in the mount (it is present in the scope simulator). Tracking earth-orbiting bodies (ISS etc.) takes additional/different support in the mount and only a few can do that.

But Starry Night's telescope controls don't support tracking a moving object so that's where the limitation is.

Thank you for your answer. I looked for too in SN Pro 6 but didn't find something powerful.

It seems that we can just follow ISS but it does not send coordinates to the telescope.

Starry Night loads the data for Stars, Satellites, Solar System "Bodies" and the like from data files. It displays them by mathematical calculations, especially in regard to the Satellites.

Reality - Starry Night nor any Stellarium or such Planetarium software does NOT track anything. Every one of the myriad of programs available will present "WHERE" the telescope is pointed when connected.

The telescope is the only thing doing any tracking. Some mounts, with the aid of additional software "can" track at the rate to stay on the ISS. Many mounts cannot. They require you to determine an intercept point to be determined, and command the telescope to slew to "that" point. By manipulating the hand control, you can select an appropriate rate to "follow" the ISS.

The latter method(s) are how some have imaged the ISS.
