A yellow filter dramatically increases contrast on lunar surfaces. Likewise on Mars. On the gas giant Jupiter, contrast between individual cloud bands is considerably increased so that they become even more visible. At apertures upwards of 200mm and in good visual conditions, details on Saturn can even be seen.
This filter can be used with apertures upwards of 127mm.
Further properties:
- Manufactured from high-quality optical glass
- Filter surface is plane parallel, polished and anti-glare coated
- Double-sided filter threads (internal/external): Multiple filters can be used simultaneously
The filter comes in a practical dust-proof case.
