**Sold**

This filter has all the characteritics of a didymium filter but it is not labeled so I cannot be 100 percent sure. When I bought the filter it was advertised as a "light pollution reduction filter" and one of the traits of a didymium filter is that it will reject sodium light (street lights). This filter also greatly enhances reds and oranges while having very little or no effect on greens or blues, which is yet another trait of didymium. This filter looks pink or rose color, which you guessed correctly, is also another trait of didymium.

Money back guaranteed if you are not completely convinced when you receive it.

$35.00 shipped - I prefer paypal (no extra fee).

Thanks for looking,

Garry Johnson
