The Ostara Moon and Skyglow filter gets a great review in the “All about space” magazine. They rate it as excellent value for money for a light pollution filter. This filter has been very popular at the North Lincolnshire astronomy society for both visual and photographic use
Available in both 1.25″ and 2″
To use the filter, you simply screw direct on to your 1.25″ or 2″ eyepiece. By reducing light reaching the eye, your views of the Moon will be more comfortable and aid increased contrast.
As a light pollution, this clever filter reduces sodium light (street lights) for enhanced views in light polluted areas
