Product Description

Celestron's Moon Filters are economical eyepiece filters for reducing the brightness of the moon and improving contrast, so greater detail can be observed on the lunar surface. The clear aperture is 21mm for the 1¼" filter. Transmission is about 18%.1¼" Moon Filter [94119-A]Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation and lessen eye fatigue. Celestron's filters are made of high quality, solid plane parallel glass with excellent homogeneity. They're anti-reflection coated to prevent glaring and ghosting. All eyepiece filters are threaded to fit Celestron's, and most other manufacturer's, 1¼" eyepieces, and offer a full 26mm clear aperture. Celestron filters are mounted in black anodized aluminum cells with the Kodak Wratten Series Number individually engraved, and come with a plastic case for safe storage. The cells of each filter are double-threaded, so they can be stacked (piggybacked) in various combinations. This allows you to create different color combinations and transmission characteristics, or to have the same color characteristic, but with a lower transmission. When stacking color filters, the effective transmission of the combination you create is equal to the product of the spectral transmission of each of the filters used.The effectiveness of the filters depends on

Cheap and gets the job done very well. Would recommend to others looking for this size filter. Images come through clearly and there is nothing to suggest you have a filter on the lens. Clear as day.

They say the best time to look at the moon is when it is a quarter to half. I looked at the moon when it was recently full. It definitely took the direct glare off allowing me to see many features for a longer period of time. Also, the craters around the edges were clear and full of shadowy contrast.

This inexpensive moon filter makes looking at the moon a much more enjoyable experience. Consider it "sun glasses" for your telescope. It reduces glare, increases contrast, and makes moon viewing much easier on your eyes, especially a full moon at higher magnification. Light transmission is about 18%.
