Technology has radically changed the contributions that amateurs can make to the field of astronomy. Using a readily-available 'hobby' telescope, off-the-shelf camera and computer equipment, plus experienced observing skills, Emmanuel I. Kardasis of the Hellenic Amateur Astronomy Association has produced the first amateur albedo map of Jupiter's moon Ganymede.
This demonstration has implications for the future role of amateur astronomers. The work will be presented at the European Planetary Science Congress in Madrid on Thursday 27th September.
[Edit for brevity. --DJW001]
To produce the images Kardasis attached a camera to his telescope and recorded a video of Ganymede. Selecting only the sharpest frames of the video allowed him to obtain a series of images when the atmospheric conditions - known as 'seeing' - were most favorable. These best images were then stacked and aligned, before being enhanced through photo-editing software.

That's pretty interesting, maybe he can map our moon as its closer and see if there are any alien bases and while he's at it prove once and for all that Nasa went to the moon in 1969.
