Astronomical filters are an essential accessory for both the visual observer as well as the imager. From toning down the brightness of the moon or the effects of false color in an inexpensive achromat, to bringing out faint details in a far off nebula, you will likely find what you need to achieve your goals here at High Point Scientific!

You've just purchased a nice fast focal ratio refractor and are blown away by its incredibly sharp and high contrast views of large nebulae and clusters, however, the moon is up tonight and you want to see what this baby can do. Inserting a high power eyepiece into its focuser and tweaking the fine focus to perfection, you are horrified at the amount of false color that you see. If this is you, then you need to check out Baader Planetarium’s 2" Semi-APO Filter! This high-tech filter will tame the contrast robbing chromatic aberration that you see with any fast focal ratio non-APO refractor, bringing those views back to heavenly status. Give one a test drive tonight and rediscover the true quality of your achromat refractor!
For gently increasing the contrast of a broad range of deep-sky objects, including nebulae and galaxies for visual work, check out Explore Scientific’s 1.25” and 2" CLS filters. These filters will provide a natural-looking background unlike the extreme contrast provided by most narrowband filters. Try one out tonight and don't let light pollution steal your skies any longer!
