The Lumicon Night Sky Hydrogen-Alpha 2" Filter can help reduce the effects of minimal pollution/haze when it comes to shooting deep-sky images. In black and white photography, maximum contrast can be accomplished resulting in dense backgrounds which, for celestial photography, can only enhance an image.
For planetary observing, color filters bring out the most detail because planets are naturally colorful. Different colors bring out different details of the planet you are viewing. A description of each color filter and what object it works best for can be found in Lumicon's Filter Specifications and Uses page.
Always remember that you want to use the darkest filter your telescope will handle. Most small telescopes up to about 5" in aperture use the light colors. The larger the telescope, the darker your filter can be. Color filters can sometimes be used in conjunction with a Neutral Density or Polarizing filter to aid in glare reduction. The more you use your filters the more you appreciate them and their affect.
To ensure that your Lumicon filter remains the world's best, the strictest quality control standards are employed throughout the production process
Each Lumicon Deep Sky Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the H-Alpha, H-Beta and OIII emission lines
