The Celestron 1.25-inch Moon Filter Set contains four filters you need to observe the Moon during its various phases. Choose the best filter to use with different eyepiece and telescope combinations. You can use the darkest filter with larger aperture telescopes and lower magnification eyepieces. You can also use the lighter filters with smaller telescopes and higher magnification eyepieces.
This kit is essential for taking the next step in exploring your telescope’s full lunar capability, or for use seasonally while using a variety of telescopes and eyepieces to observe the Moon.
What You Get:
-
Three Neutral Density (ND) Filters: ND96-0.9 13% T, ND96-0.6 25% T, and ND96-0.3 50% T —These dim the entire visual spectrum from 400 to 700nm equally. The ND96-0.9 filter transmits 13% of the incoming light, the ND96-0.6 transmits 25% and the ND96-0.3 transmits 50%. They do not impart any color to the Moon but reduce lunar brightness.
