Is there any possibility I could make a print screen from earth.nullschool.net and set as a background to my opencpn? A graphic background to my plotting would be a very big help in weather observation and trip planning.
If you happen to know which projection is used (e.g. by requesting this info from the people who run the website) AND if this projection is compatible with those available in OpenCpn, the answer is a theoretical yes..

The projection used is not supported. You would be better off getting the source code, and modifying it to use the mercator projection. Then writing a plugin you could keep the animation ability.
