This suggestive and sharp Contextual Image (or "CTX Frame", for short) of the Dwarf Planet 1-Ceres, taken by the NASA - Dawn Spacecraft on January,  1st, 2016, shows us the North/Eastern Rim of Sintana Crater. The Crater's extremely steep Rim is shadowed in this particular view. The Crater's density along this Area of Sintana's Rim (both Inner and Outer) appears to be roughly the same, and it is dominated by small Impacts. Sintana Crater was imaged earlier during Dawn's Mission, but from an higher altitude. Just out of curiosity, this Impact Crater was so named after a Deity from Colombia which is said to have produced fertile black earth for sowing crops.


The frame is centered at about 45,6° South Latitude and 49,2° East Longitude. The NASA - Dawn Spacecraft captured the scene during its Low-Altitude Mapping Orbit (or "LAMO", for short), from an approx. altitude of 234 miles (such as about 376,58 Km) above the Surface of 1-Ceres. The Image Resolution is roughly 115 feet (i.e. about 35,052 meters) per pixel (---> Picture Element).


This image (which is an Original NASA - Dawn Spacecraft's b/w and NON Map-Projected frame published on the NASA - Planetary Photojournal with the ID n. PIA 20310 - DAWN LAMO Image n. 21) 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.
