      4.0 High quality, but still too bright

      Pros:

      Cons:

      Comments:

      This item is great for small aperture telescopes but for larger apertures the image is still too bright for anything more than the smallest of crescent moons and for planetary viewing. For larger aperture scopes, I would recommend a 13% ND or Moon Filter that allows only 13% of visible light.

      Telescopes used with this filter: Celestron C-11 CF (XLT), 12" Meade Lightbridge, 14" custom truss dob.

      Bottom Line: Would you recommend this item? Yes

      Cons:

      Comments:

      This LUMICON FILTER reduces the intensity of the moon's light to allow maximum enjoyment of your observations. Details of the moon's surface such as craters, craterlets, plateau features & ridges are sharply rendered. Optical quality can not be faulted. Telescopes used with this filter. Saxon 5.2" newtonian, Stellarvue SV115t20 & GSO 10" Dob
