FILTERS ( 5 )

Nothing can make or break a successful viewing session like having the correct filters! Filters can remove the adverse effects of street light and atmospheric pollution or can increase contrast to bring our subtle detail.

Color glass filters have a variery of uses, from reducing eye fatigue to bringing out detail in planetary views. Cross polarizing filters act like a continuously variable neutral density filter to reduce eye strain and to take advantage of the unique properties of polarized light.

Light Pollution - Nebular Filters Street and Atmospheric light pollution is a major problem almost everywhere in the U.S. these days. Imagine having a filter that removes or reduces these unwanted effects and acts as a nebular filter, enhancing the subtle details of these delicate structures! This filter does both. Available in both 1.25 inch and 2.00 inch screw-in formats, this filter fits all standard eyepieces. Size : 1.25 inch (plus US$79.95) 2.00 inch (plus US$119.95) Unit Price: Quantity:

Variable Polarizing Filter A "Variable Polarizing Filter" is like a continuously variable neutral density filter that takes advantage of the unique properties of polarized light. This Variable Polarizer makes a superb variable density Moon Filter! See why it's instructional and fun to experiment with polarized light! 1.25 inch size only. Price: US$ 34.95 Quantity:

Neutral Density Filters It's like having a pair of shades for your telescope... (but these are NOT solar filters!) Neutral Density Filters attenuate the intensity of light uniformly across the visual spectrum. Makes really bright objects (like the full moon...) more viewable. Lower number means more light reduction. Click the "More Info" Icon for More...
