Focus the telescope with the appropriate eyepiece and lock the focuser. Remove the eyepiece, attach the camera to it and replace it, being careful to not disturb the focus. Experiment with combinations of eyepiece and camera zoom to produce the desired results.
Be sure to cancel the flash mode on the camera. Set the camera to focus for infinity, shutter priority, ISO 100 and remote or self-timing. Although the Moon appears to be solely shades of gray, do not set the camera for black-and-white photography. You may lose some detail but you can change the image to black-and-white when you process it in your computer. For photographs of the Moon at low magnification, depending on the phase, use shutter speeds from 1/80 to 1/50 of a second. Then take several photographs at each of several increasing magnifications. For the highest, the shutter speed may be as long as V2 second with an 80-mm refractor. Take high magnification photographs of overlapping sections along the terminator. To be sure, it takes some experimenting and not a little patience to become familiar with the procedure for getting excellent photographs, but is well worth the effort.
