Apertura 25% Transmission 1.25" Neutral Density Filter

A neutral density filter can be your best friend when viewing bright objects, especially the Moon!  In fact, many so-called Moon Filters are actually neutral density filters.  A neutral density filter does not change the color of the moon or other objects, it just lowers the light coming to your eye so all that brightness doesn't keep you from seeing smaller or fainter details. In other words, using a ND (neutral density) filter on the Moon is like using sunglasses on a bright, sunny day!

The Apertura ND96-0.6 filter has a transmission of 25% and is mounted in a 1.25" threaded cell.  Simply thread the filter onto the 1.25" diameter barrel of your eyepiece or Barlow lens.  You can stack most 1.25" filters together (best if from the same manufacturer) if you like, but just remember, the more light you cut out by stacking, the less light there is on the subject.  The larger your telescope aperture, the more you can get away with stacking filters.

All Apertura filters come in a plastic box for safe-keeping.
