The 2" Ice Variable Polarizing Filter allows you to control the amount of light transmitted through to your eye so you can tailor it to the brightness of the object you're looking at—reducing the brightness and glare on celestial objects like the moon, Venus, and even bright double stars.

This filter does not alter the color of the object you're observing, making it a great choice for astroimaging, especially when imaging the surface of the moon. By reducing the brightness, lunar details become more pronounced and defined. This filter can also be used to darken the blue sky background when hunting for planets like Venus or Jupiter during daylight, making the planet stand out from the background. Simply rotate the filter's lower ring to adjust the light transmission from just 1% (blocking 99% of incoming light) up to as much as 40%. Having this level of control over the filtration allows you to precisely set it to a specific target and current viewing conditions so you can get the best view possible. Standard threads on both sides allow it to be installed on just about any 2" eyepiece and stacked with color or specialty filters to further refine and enhance the viewing experience.

Related Questions and Answers

Q: 1. Does the filter separate so you can place one end on the diagonal and the other on the eyepiece for easy adjustment?

A: Yes, the lenses of the Ice Variable Polarizing Filter (1.25") can be separated.

Q: 2. Is it possible to see through plastic with this filter on a Nikon Z7ii? Or does it require other special equipment?

A: The Ice 77mm HB760 Infrared Filter has a filter factor of ~1000x and ~10 stops of ND. You will not be able to see through the glass unless you are aiming the filter directly at a bright light.

Q: 3. How well will this work with a near-IR film like Ilford SFX?

A: The Ice 52mm HB760 Infrared Filter blocks UV / Visible Light under 760nm. This will not work with Ilford SFX 200 Black and White Negative Film that only has sensitivity up to 740nm. Near IR film does not have the sensitivity to work with this filter.

Q: 4. Is the Ice Lipo Light Pollution Filter (2") made of plastic or glass?

A: The Ice Lipo Light Pollution Filter (2") is a glass filter.

Q: 5. Does this come apart into two pieces like the Orion so you can put one half on the eyepiece and the other on the diagonal?

A: No, it dose not come apart.

Q: 6. Whats the difference of this circular polarizing on the linear? Is circular polarizing works on auto-focus SLR cameras, because I have read about that they are not recommended for auto-focus SLR cameras. How true?

A: Circular Polarizer are designed for autofocus cameras. Most lenses cannot autofocus with a linear polarizer. If you want to use an autofocus lens you should choose a circular polarizer.

Q: 7. Will this work for a Nikkor ais 24mm f2.8 lens?

A: Yes, since it has a 52mm thread but for manual focus lenses, a linear polarizer is more appropriate, but you can still use a circular polarizer.

Q: 8. Is this filter multicoated?

A: No. This is not Multi-Coated.

Q: 9. hello how many lens elements are housed in a standard 58MM filter of this type

A: Circular Polarizers and polarizers in general are composed of two flat pieces of glass (as opposed to elements which are convex/concave optics used in a lens).

Q: 10. I have a Nikon D5500 with a lens 18- 140mm mm . I purchased this filter and It does not fit !!!! :-( Am I doing something wrong? can I exchange it?

A: I believe the filter thread diameter for this lens is 67mm, not 77mm. You should be able to return it if within the allowable time frame. Good luck.
