Uranus and Neptune - True color (2015.09.25)

Technical card

Resolution: 600x481

Locations: Balcony in the apartments, Podolsk, Moscow region, Russian Federation

Description

I decided to spend one night for color imaging. The goal was to get correct color of the planets.
I have performed the following to obtain true color: use of dispersion corrector, background subtraction and setting the color balance with artificial white field.

Neptune:
In general, as expected, the planet is almost monochromatic. However, the south side noticeably lighter. And it is lighter only in red and partly green, so the polar region is whiter.

Uranus:
Color of the planet is very close to the color of Neptune.
Belts are clearly visible in red channel, so it is not featureless!

It is surprise for me that color difference between planets is so weak. Note: I believe that to see this difference clearly your monitor must be precisely calibrated to 6500 K or slightly lower.
