Telescope Light Pollution Filters Review

Basically the filter s job is to reflect or absorb the wavelengths of light that are generated.

Telescope light pollution filters review. A light pollution telescope filter is probably the most generic of these types of filters and is designed to block out certain wavelengths of light such as the light being created by sodium vapor mercury fluorescent and other man made sources of light that are typically found in outdoor lighting. Lets see if this light pollution filter review helps. When compared to filters that get inserted in camera bodies or telescope eyepieces the filters tested here are more for casual night photography because they screw onto the front of the lens like any other filter. These can be screwed on to a camera adapter eyepiece or onto a diagonal.

The broad band light pollution reduction lpr filters are designed to improve the visibility of a variety of deep sky objects by blocking out the common mercury vapor sodium and some other emission lines from man made or natural sources which contribute to light pollution while letting through a broad range of other more useful wavelengths. Light pollution filters are typically 1 25 or 2 round filters that screw into your telescope to reduce the effects of light pollution on your viewing or imaging. The astronomik cls city light suppression filter is the perfect first filter for astrophotography whether it is through a telescope or with a camera lens. Read our definitive guide on visual and imaging astronomy filters to learn about telescope filters and their applications.

Light pollution filters therefore swing the balance back into favor of those objects in the sky. The ability for us to observe objects in the sky entirely depend on how much light we can pick up through our apparatus telescope binoculars etc. This filter has a proven track record of consistent results under city light pollution and one of the first light pollution filters i used with my camera. Telescope filters for astronomy can be confusing.

What is a light pollution filter. Although the astro multispectra filter is marketed as a filter for astrophotographers i wanted to find out if this filter is any good for so called nightscape shots too. Light transmission can be adjusted from 1 percent to 40 percent just by rotating the eyepiece filter housing. A quality light pollution filter will allow the important colors and light emitted by your astrophotography subject to reach the camera sensor without the nasty brown glow of a washed out sky.

The design of the filter includes layers that block specific bandpass lines of the visible spectrum.
