Telescope Light Pollution Filters Review

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

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. 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. Read our definitive guide on visual and imaging astronomy filters to learn about telescope filters and their applications. Light transmission can be adjusted from 1 percent to 40 percent just by rotating the eyepiece filter housing.

What is a light pollution filter. Telescope filters for astronomy can be confusing. Light pollution filters therefore swing the balance back into favor of those objects in the sky. Basically the filter s job is to reflect or absorb the wavelengths of light that are generated.

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. 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. 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.

Whether you re filtering out light pollution or enhancing planet colors we know how to help you. Lets see if this light pollution filter review helps. 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. These can be screwed on to a camera adapter eyepiece or onto a diagonal.

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.
