Digitally Painted Mistress of the Night
image by Maximilian Teodorescu, Cota 1000 (SInaia), Romania
See anything odd about this first quarter image? Note how much detail is visible in the Earthshine portion, and the good exposure all across the sunny side. That is because Max used software to capture and produce a High Dynamic Range saturated-color image that uses a series of exposures to supply detail in bright and dark areas and everything in between. Max notes that the Earthshine side has a blue cast, and I can just glimpse it, especially along the southwest limb - I wonder if that is a real coloration of Orientale ejecta? On the Sun-lit side the blue-gray, titanium-rich lavas of Mare Tranquillitatis seem to be rise above the surface. Their well known boundary with the red, here brownish, lavas of Mare Serenitatis appears quite abrupt, as we know it is from Apollo images. Windows, or kipukas to use a Hawaiian word favored by volcanologists, show up at left center of Serenitatis, explaining the sharp curved boundary of lavas associated with Lamont. Some patches of blue-gray lavas crop out along the eastern edge of Fecunditatis and perhaps also towards the southwest of that mare. Note that the Australe lavas are brown, in fact, even browner than those in Serenitatis. I hope Max and others will continue these experiments. The Imbrium color contrasts should be spectacular.
115mm F/7 APO Refractor, Canon 550D, ISO 100. 174 frames were processed for the finale image, with exposure times ranging from 5 seconds to 1/160s.
