Use is made of a homemade 20 cm Dall-Kirkahm at f/28 equipped with a Philips ToUcam Pro.
A 0.5° wedge prism was employed to compensate the dispersion. Also an IR blocker is used.
Each image was made by stacking 4000 frames each taken with a 1/25 sec exposure. since the shooting was made under a hazy sky .
Since the original B channel of the ToUcam colour image admits an intrusion of longer waves (>500mn) of G, we here provide, in addition to B, another processed image B - 0.3G, that is made by subtracting 30% of G from the original ToUcam B ingredient.
The mornig side of the spc is brighter. The Xanthe evening white cloud goes up to Ophir-Candor. An atmospheric difusion is visible at an area of Syria Planum following Solis L.
