Does anyone have any suggestions for software (web-based or Mac-compatible), books, tools, or other techniques for understanding motion of celestial bodies for photographic purposes? Thanks in advance for any suggestions!
In addition to the TPE and Stellarium, I use an app on my Android Smartphone called Sun Surveyor
, and it offers an 'augmented reality' feature which plots the Sun/Moon position and trajectory over what your built-in camera is looking at. It recently has also been released for iPhones
For the understanding and calulation of positions and trajectories you could check out:Astronomical-Algorithms by Jean-Meeus
