The very low Albedo Feature (---> Region) known as Senkyo, is slightly visible here, through the haze of Titan's Atmosphere. Prominent dark areas found in Titan's Equatorial Region appear to contain vast and continuous Dunefields, discovered by the Cassini Radar Experiment and likely composed of Dust Particles that drop from Titan's unique, smoggy Atmosphere. The almost circular Feature visible to the left of the image center appears to belong to the Surface of Titan, but it could also be the result of either a peculiar configuration of some low Clouds, or a bizarre-looking image artifact. This view looks toward Saturn-facing Side of Titan and is centered on Terrain at about  South Latitude and 345° West Longitude. North on Titan is up, and rotated 10° to the right.


The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on October 12, 2009, using a spectral filter sensitive to Wavelengths of Near-InfraRed Light centered at 938 nanometers. The view was acquired at a distance of approximately 296.000 Km (such as about 184.000 miles) from Titan and at a Sun-Titan-Cassini Spacecraft, or Phase, Angle of 11°. Image scale is roughly 2 Km (such as a little more than 1 mile) per pixel.


This picture (which is an Original NASA - Cassini Spacecraft b/w frame published on the NASA - Planetary Photojournal and identified by the n. PIA 11636) has been additionally processed and then colorized, according to an informed speculation carried out by Dr Paolo C. Fienga (LXTT-IPF), in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Cassini Spacecraft and then looked outside, towards the Saturnian moon Titan), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements present in the Atmosphere and on the Surface of Titan, each having a different Albedo (---> Reflectivity) and Chemical Composition.


Note: it is possible (but we, as IPF, have no way to be one-hundred-percent sure of such a circumstance), that the actual luminosity of the Albedo Feature seen in this frame would appear, to an average human eye, way lower than it has been shown (better yet: interpreted) here.
