Home Filters Lunar & Planetary Filters Baader ND0.9 Neutral Density Filter 2 Inch
Premium 2" neutral density filter that far outperforms standard ND type filters due to advanced coatings and optical polishing. This results in no ghosting, stray light or reflection issues that reduce and effect contrast for perfect energy management during Lunar and Solar observation (with correct safe Solar filters). This 2" version is ideal for use with 2" eyepieces when viewing the Moon at low powers with wide fields.
A far superior 2" Moon filter that will not degrade the image even at very high magnifications, a perfect companion for serious Lunar observers.Planoptically polished with Phantom Coating Group Multi-coatings.Neutral Density (Grey) Filter 2" multi-coated / OD 0.9 T=12.5% (optically polished)
Baader ND0.9 Filter 2" Can't go wrong with Baader filters, top quality. Even though I only use 1.25" eyepieces I like to use 2" filters in the nose of the 2"-1.25" adaptor before the diagonal and being further away from the eyepiece the filter glass has to be super flat. The Baader filters are. (10/10/2020) -
