| This is the image of a 6 day old moon taken using a digital camera (Sony Mavica) handheld to the eye piece of a Meade ETX 60 AT telescope at about 28X magnification.To get an idea of some of the details that are seen here, take a look at this image. What makes the moon appear pitted with craters is that the moon, unlike the earth, doesn't have an atmosphere but does have gravity (about 1/4th that on the earth) which causes meteors to reach its surface without burning up. This causes these craters, though they might have happened over thousands (or more) years, mostly during the early period of our solar system formation. | |||||||||||||||||||
| Astrophotography can be a little hard and intimidating at first, especially when taking deep sky images. However, to start with one only needs a simple SLR camera with a tripod and a cable release to lock down the shutter for extended exposures. This particular picture� captures the rotation of the stars (or actually, the rotation of the earth) around the north celestial pole. The small star in the middle (actually the smallest circle) is that of the pole star (part of the little dipper asterism). The two diagonal streaks are airplanes passing through the field of view. 50mm lens ~42minute exposure on a ISO 400 film. |

| This is the 7/8th day moon taken with a SLR camera using 200 mm telephoto lens mounted on a standard tripod, 1/125 sec. exposure on ISO 400 film. Although the seas ('mare') are visible, in order to get detail, one can say that a telephoto lens of at least 300mm or more is necessary from this picture. | |||||||||||||||||||
