Recently, a netizen used a small telescope, connected to the iPhone 4 successfully photographed the moon. The user used an iPhone 4, a Borg_s Pencil Borg (175mm f/7) telescope and a Vixen_s LV5mm eyepiece to find the position of the moon and start shooting.
The user has sharpened the final image, but still retains enough resolution to see some detail in the photo.
Although the final effect can not be compared with the shot with professional equipment, but for the average user, it is very good. You can try to use a general DSLR camera with a telescope to shoot the moon, and there will be good results.
