Baader U-Filter 2″ (ZWL 350nm).
UV Filter 2″ – for Venus photography
The cloud structures of Venus are included for observation
hardly accessible to amateur astronomical devices. The Baader Venus filter
lets through only the light in which the cloud structures are visible,
the UV light. This makes it possible to photograph Venus in UV light,
Structures are already visible in smaller devices. Each additional
Light transmission is stopped. With this, the structures of
Atmosphere of Venus first visible.
