    Celestron Mars Observing Filter - 1.25"


    This Celestron 1.25" Mars Filter combines the advantages of red and blue filters in a single filter, bringing out an abundance of detail while enabling maximum light transmission for brighter views. With multiple coatings, this high quality glass filter is able to maximize light transmission at certain wavelengths in order to highlight a substantial amount of detail in the Martian terrain.

    Eyepiece filters enhance contrast via selective filtration, enhance definition and resolution, and reduce glare and light scattering all while minimizing eye fatigue. Attach the filter to an eyepiece by simply fastening the filter's male thread to the underside of the eyepiece barrel. Next, insert the eyepiece and filter into your telescope's eyepiece holder.


    Mars Opposition History and Facts

    Get ready to see Mars in incredible detail. Observe Mars this summer as the planet will be noticeably brighter from early July through early September (July 7th to September 7th). The best night to view Mars is July 28, 2018.

    Mars won't be this close to Earth again until 2050! The last time the red planet was this close and this bright in the night sky was during the opposition of 2003. This is a perihelic opposition, meaning both Earth and Mars are near the Sun, creating optimal conditions for astrophotography.
