The Opticstar Light Pollution Filters improve contrast for all types of telescopes.
These high transmission filters are especially effective on the Moon and planets
where they will show additional detail, they will also darken the sky background
to enhance many deep sky objects like galaxies and nebulae against a darker sky
The filter comes in 1.25” and 2” formats and sits in a CNC machined cell that is
threaded for filters. This allows you to stack additional filters on either side
of this filter. The filter has been designed to offer a maximum open aperture.
