You can use any planetarium program, but that can be quite difficult. I upload uncertain starfields to
nova.astrometry.net, which can usually solve the field.
I don't think it's necessary in this case, however. That is clearly the handle of the Big Dipper oriented vertically above the outhouse, and two of the cup stars at the top of the frame. You can quite easily make out the visual double of Mizar and Alcor. So the view is to the northeast.
