Vixen's Moon Filter reduces the brightness of the moon and improves contrast, so greater detail can be observed on the lunar surface.
Most telescopes will not reveal as much detail of the full or nearly full moon as they will when the moon's waning back to a new moon.
This filter attaches to any 1.25" (31.7mm) eyepiece threaded to accept filters.
- Clear aperture of 19mm allows more filtration than some less expensive moon filters
- Weighs just 10g (~4/10ths of an ounce)
- Threaded to attach to all 1.25" style astronomical eyepieces
