The 2x Power Doubling Lens doubles the magnification of any eyepiece that is used with it. The lens goes in between the telescope and the eyepiece you are using. In addition, this lens also features integrated T-threads that allow you to attach your DSLR camera to your telescope for high magnification lunar and planetary photography. (Note: to take advantage of this feature, you will need to purchase an optional T-ring that fits your specific camera body and thread it onto the T-adapter. Celestron offers Canon and Nikon T-rings.)
Eyepiece filters reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, and reduce eye fatigue. These filters are designed to fit any Celestron 1.25? eyepieces. To attach the filter onto an eyepiece, simply thread the male thread on the filter into the bottom of the eyepiece barrel. Then insert the eyepiece (with filter attached) into eyepiece holder of your telescope.
