Sorting Out the Rays
image by Philippe Tosi, Pic du Midi observatory, France
High Dynamic Range (HDR) softwarecombines multiple exposure images to highlight detail across the whole brightness range. Here Philippe applies it to a full Moon view of Tycho and its dark collar. This technique appears to bring out the individual raylets that often get visually fused into a confusing bright nexus. And it shows darker materials underlying the rays on the right side of the image. HDR imaging may be a new approach to detail mapping and ultimately characterizing and classifying lunar ray systems.
