Filters Filter Dark Green #58A 1.25"

Green filters dramatically increase contrast between red and blue regions of cloud structures on the gas planets of Jupiter and Saturn. When used to view the Earth's moon, it shows ray craters more clearly.

These filters should only be used for apertures upwards of 200mm.

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.
