I used a Tamron SP AF 1.4X teleconverter coupled to the Nikon 80-400 VR lens on a Nikon D70s. The lens was mounted on a carbon fiber tripod. The Tamron TC works great and allows AF to work on the 80-400 lens. This setup is equivalent to an 840mm lens in 35mm film!
Note: The moon is not this big in the viewfinder, I cropped some of the dark sky from the original picture.
