Key to Sizes of LBT First Light Images

This image shows how the various displayed images were cropped from the First Light image. The circle indicates the 0.5 degree diameter of the full moon. North is at the top before cropping.

This image shows the extent of the 4 science CCD detectors in the focal plane of the Large Binocular Camera. Again the circle indicates the diameter of the full moon. Stars and galaxies are visible outside the detector boundaries because of the dithering of the ten sub-images used to create the final image.
