Strange as it may sound, the cheapest cameras are also the best when it comes to imaging the moon (and other members of the solar system). The king of the webcams is the Phillips ToUCam Pro (740k and 840k models) which is available for less than $100, has a removeable lens and requires a $20 adapter so that it can be dropped into a star diagonal (I use a black Kodak 35 mm film canister which perfectly doubles for an adapter and fits perfectly into a 1.25" diagonal). The strength of these web cameras and which pulverizes the more powerful and expensive CCD and digicams is their ability to continually sample our target of interest so that brief moments of good and steady seeing are not only captured but are recorded in droves due to the high sampling rate, thus allowing for a wealth of material to increase the S/N {Signal-to-Noise -- ed.} ratio! Who says the brute force method (vis a vis incessant sampling) is not preferable?!
