Minus Violet Filter

 

This is the Sirius Optics MV1 Minus Violet Eyepiece Filter.

 

Sirius Optics have produced a specialized corrective filter that greatly reduces the false colour fringing of blue-violet light.

This halo effect is most noticeable in relatively low cost achromatic refractor telescopes.

The MV1 eyepiece filter is a cost effective solution that does not appreciably change the viewing colour.

We feel the MV1 is a necessary filter for the refractor telescope market.

It both enhances viewing pleasure by reducing the false colour, but also eases focusing.

There is less unfocused light, which tends to make it easier to find that sweet spot of focus.
