Compass in hand, I was prepared to make this exact photo with all the telephoto power I could muster on the evening the super-moon was to rise. When it lifted above the misty horizon, I found I'd miscalculated by about 10 degrees. I had to quickly shoot my lighthouse scene across the bay, then rotate the lens a bit to the right and shoot the big moon. No proportional change here. I simply layered one image over the other to get the moon over the lighthouse. The key is in having a known-size subject in the distant foreground and lots of telephoto power.
