Most Lunar and planetary images taken at the 3towers Observatory use either a Nikon D100 digital single lens reflex camera for widefield imaging or a web cam attached to a telescope for prime focus imaging or imaging at prime focus combined with a Barlow lens. The seeing conditions at the 3towers Observatory are usually mediocre at best so that its lunar and planetary imaging does not compare with the incredible results now being obtained by many amateur astronomers worldwide. Nevertheless, the significant improvement in planetary and lunar results available from modern web cams, digital cameras, and software techniques allows almost anyone with modest equipment and seeing conditions to obtain results that rival or exceed those of the best planetary images obtained on film in the recent past.
