Tiffen 4x5.65" Low Light Ultra Contrast 2 Filters - Bright lights or sunlight create problems when the ratio between the highlight and shadow areas is beyond the latitude of the film.

If you expose for the highlights, the shadows appear without detail. If you expose for the shadows, the result is washed-out, overly bright highlights. Contrast reduction is achieved by lightening shadows without overexposing highlights or by darkening highlights without darkening shadows further.

Tiffen Low Light Contrast filters are more effective in dealing with contrast in lower light scenarios

Tiffen Ultra Contrast filters work by using the ambient light surrounding the image area as well as the light in the actual image area itself

They lower contrast uniformly, with little or no loss of sharpness, throughout the scene even when there are varying degrees of brightness within the image

Shadow areas are opened up, revealing more detail, but without any flare or halation from direct light sources or bright reflections

Even direct shooting into the sun produces no flare or halation

Q: 1. What is the light transmission?

Q: 3. Can I screw on the Nikkor's lens hood if I attach to the lens a Tiffen filter? (I have the 24-120mm 4.0 Nikkor's lens)

A: The filter does not add any additional width to the front of your lens. If you can get your lens hood over the end of your lens without the filter, you should be able to do the same thing with the filter.

Q: 4. Has anyone used this for Astrophotography with a DSLR and coma corrector?. I use an 8in Newtonian.I live in light polluted area and can only get 2 minutes with ISO 400 and 50 sec w/ ISO 800. Will this filter help?

A: This filter would help definitely. Just make sure you have the right size eyepiece size for your scope. This model is the 2 . We also have a 1.25 size too. Here is the link to the smaller size: http://bhpho.to/1Luj0jC

Q: 6. My old Celestar came with five Parks 1.25" filters, including their "ALP" (anti-light pollution) filter. My yard gets heavy light pollution, so I'd pay for a more expensive filter if I were sure it would give me much better performance. Any filter comparisons out there?

A: The Celestron filter is effective in light pollution situations. However, I cannot compare it to the filter that you already have and don't know if it will be any more reducing of light pollution in your yard. My suggestion is to buy the filter and compare.

Q: 8. What is the differences between this model and http://www.bhphotovideo.com/c/product/398871-REG/Schneider_68013038_138_mm_True_Linear_Polarizing.htmlIt seems like its just different descriptions but the same product. The only noticeable difference is a 10 year warranty on the more expensive model. What exactly does this cover? Does it cover it breaking?

A: Basically, there are two types of Polarizing filters; Linear and Circular. Linear are used for manual focusing as they can confuse AF sensors. Circular filters are designed for AF lenses and cameras but can be used on manual focus cameras as well. For more details on the two, please see: http://bhpho.to/MF21zoThe Schneider 138mm True-Linear Polarizing Glass filter is optimized for motion picture and television cameras. Having an extinction ratio of ER 374, the Schneider True-Pol is 12-times more effective than other polarizing filters. The 138mm Circular Ultra Polarizing Filter from Tiffen is a similar filter yielding a more intense look to your images and is designed for AF cameras. Because of manufacturing differences, circular polarizing filters cost more than comparable linear filters. Both filters come with ten year warranties that cover manufacturing or workmanship defects.
