I use Stellarium for this, once set-up with your location you can display the sky as viewed from your site at any given date/time and show both the RA/Dec grid and the local Azimuth/compass bearing grid.
I googled how to set-up my own horizon, kept it simple with just a list of bearings/elevations to give a simple artificial horizon so I know when things disappear behind trees/mountains. If you want, you can replace the horizon with your own panoramic photo.
