Plate-solving is useful -- especially when you use it to correct a telescope's position in real-time . You also can feed the solver an existing photo and manually read the results but using the output can be cumbersome. Manual copy & paste coordinates of input fields of tools like Stellarium helps, but that approach isn't very user friendly. Here's a different take on this -- solve the image and instantly get the sky map of that region. Again, this is using mostly freeeware tools.
