14 Inches of Tycho
image by George Tarsoudis, Greece
I'm going to have to get a laptop with a larger screen. With amateurs now using larger scopes and larger format cameras, lunar images are
out-growing my 11" Air. George has started producing large scale images with excellent resolution. This example shows why it wouldn't have
been safe to be anywhere near Tycho about 110 million years ago. Nearly everywhere here the surface is pitted, streaked and coated with
what must have been hurricanes of ejecta. A prominent crater chain streaks across the northwest corner of the image. The floor of Tycho in
George's image seems similar in detail to the LRO QuickMap view at 500 m/pixel resolution. Smooth patches of impact melt on the floor
are well seen, but to recognize that the rough areas are also covered/immersed in melt requires better than 100 m/pixel resolution. There
remains some need for spacecraft.
