Telescope Light Pollution Filters Review

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.

Telescope light pollution filters review.

These can be screwed on to a camera adapter eyepiece or onto a diagonal. Light transmission can be adjusted from 1 percent to 40 percent just by rotating the eyepiece filter housing. Basically the filter s job is to reflect or absorb the wavelengths of light that are generated. Read our definitive guide on visual and imaging astronomy filters to learn about telescope filters and their applications.

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 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. The difficulty is that knowing what light pollution filter is best can be quite difficult. 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.

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. Light pollution filters therefore swing the balance back into favor of those objects in the sky. The design of the filter includes layers that block specific bandpass lines of the visible spectrum. What is a light pollution filter.

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. Whether you re filtering out light pollution or enhancing planet colors we know how to help you.

Telescope filters for astronomy can be confusing.
