Ralf Vandebergh(250mm Newton)|
Attached are images of Uranus,obtained on Aug 14,using red,green anb blue filters.
seeing: fair-good/transp: fair/some clouds.
Just like the observations from Aug 7,the red image is the one showing most
albedo variations.(combination of 3 avi's),green and blue are single avi's.
10 inch Newtonian & ATK-1HS camera)
Attached are some high contrast processings showing the brightening of the SPR of Uranus on
Aug 14. Left: RGB-high contrast.Right: RGB-with more share of red light(and darker exp).
This is an image of the Uranus-moons situation on Aug 14, taken in primary focus;
10 inch Newtonian and ATK-1HS camera (33x 2.3 sec).
This animated gif is made of red light images and gives an impression of Uranus
in good seeing.As visible,there is still enough turbulence due to the small disk.
In worse seeing, when the planet's edges are not sharp,it will be impossible to
see anything on it.
10 inch Newtonian and ATK-1HS camera with R610 filter)
This is a composite of a highres image of the Uranus disk and a standard image of the moons in right proportion
of disk-size/moons distances, and the right orientation.Aug 14)
10 inch Newtonian and ATK-1HS camera with RGB filters for disk/without filters for moons.
