Today more about that new Jupiter-U filter of mine vs. the Baader U (Venus) filter. Shots taken today at the wonderfully blossoming Hermannshof, Weinheim, Germany.

The Jupiter-U is a shorter wave filter (center is 340nm) and its transmission is this, as compared to the Baader (Venus) U filter (red line):
Here now some results of today:

and another one:

very subtle tone differences get visible in comparison to the Baader-U filter.
Stay tuned, more will follow on that fascinating subject...
