The Moon With A Telephoto Lens

This image of the moon was obtained on January 3, 2005 using a Canon 1D Mark II 8-megapixel digital camera, a 500 mm f/4 L IS lens with 1.4 and 2x teleconverters. The total focal length is 1400 mm for a full scale of 1.2 arc-seconds per pixel. Three raw images were converted and added to increase the signal-to-noise, then the image was increased in size by 2 times. The exposure times were 1/125 second at ISO 200, f/11.2 (this is wide open on the 500 mm f/4 lens with the teleconverters). This larger image was then sharpened with Adaptive Richardson-Lucey Restoration with a 11x11 box, 10 iterations, noise level = 2 standard deviations, then a second pass with a 7x7 box, 10 iterations. Final adjustments included curves stretch and unsharp mask. For an image with the original camera resolution, 1.2 arc-seconds per pixel, 1295 x 1829 pixels (260 KBytes), CLICK HERE. Note: this large image is limited by atmospheric turbulence.
