As long as the Skyatlas in the Seestar app does not allow you to specify the observation time, I like to use the separate Skyatlas app from ASi mounts for planning. I can also specify the FOV of the Seestar there under Custom, but unfortunately not the alt-azimuth mount of the S50. It would be great if the SkyAtlas app could include the S50 as a camera (with the mount's FOV always vertical).
