Your card will only be charged once item ships.
The Opticstar 1.25" Light Pollution Filter improves contrast for all types of telescopes. This high transmission filter is 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 background.
The filter 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.
