From the dark area to the upper left of the moon's face, you can see that this image was taken just a few hours before it was truly a full moon. For previous photographs of the moon, I would use the same focusing screen in my camera as I used for other astrophotographs; a plain matte screen. Focusing on the moon would be difficult at best with this screen and I would have to "bracket" my focus point for several exposures to be sure I would get a decent image. Even with bracketing it seemed to be a hit or miss situation. For this picture, however, I used a different focusing screen in my camera; one designed for photomicrography (photographing through a microscope.) This focusing screen has a clear circle in the middle which, if you focus your eyes at infinity, will give you a better image of the object you are trying to photograph. The trick is to focus your eyes at infinity and not on the other areas of the focusing screen. When I processed the film, half of which was taken using the old focusing screen and the other half with the new, I could see great improvement by simply holding the processed negatives up to the light! If you use a Nikon camera for astrophotography, I can definitely vouch for the type C screen. This image was photographed using a Celestron CG-11 telescope using an f/6.3 focal reducer giving a focal length of about 1700 millimeters. The film used was Kodak TMax 100 developed in HC-110.
