The moon. Final processed image of the moon taken with an 8-in. refracting telescope. The image is a seamless mosaic of two different images, which were properly focused and exposed during the image acquisition session. Afterwards, the image was reduced and processed to increase the level of detail and the contrast, which enhance the features on our natural satellite. Due to short exposure times and low noise levels, calibration images were not required for the moon
