This is an Extra Detail Magnification (or "EDM", for short) obtained from a Contextual Image (or "CTX Frame") of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on February, 12th, 2016, that shows us a Region very close to the center of Ezinu Crater.


Ezinu Crater is characterized - among other things - by the presence, on its Floor, of a network of - relatively deep - Canyon-like Features (---> the largest and - probably - deepest one is seen here). Ezinu Crater measures about 72 miles (such as roughly 115,87 Km) in diameter and it was so named after the Sumerian Goddess of grain


The Original View was centered at approximately 42° North Latitude and 197° East Longitude. The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 240 miles (such as about 386,2416 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 120 feet (i.e. about 36,576 meters) per pixel (---> Picture Element).


This image (which is a crop obtained from an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20560 - DAWN LAMO Image n. 65) has been additionally processed, extra-magnified to aid the visibility of the details, contrast enhanced and sharpened, Gamma corrected and then colorized (according to an educated guess carried out by Dr Paolo C. Fienga-LXTT-IPF) in Absolute Natural Colors (such as the colors that a normal human eye would actually perceive if someone were onboard the NASA - Dawn Spacecraft and then looked ahead, towards the Surface of 1-Ceres), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
