Designed by Baader Planetarium, this exceptional set of filters elevates your stargazing experience by surpassing the standard of common "flame polished" filters. Crafted with a fine optical polish and 2mm thick glass, these filters can be seamlessly integrated into your optical path without introducing any astigmatism or defects. The set includes three long-pass and three genuine bandpass filters, each meticulously designed to enhance specific planetary surface details and nebula observation.

Exceptional Quality and Performance

What sets the Baader Premium Color Filter Set apart is its unparalleled quality. The substrates are free of striae and polished to within 30 seconds of arc, ensuring the elimination of double images and ghosting. Each filter boasts a 7-layer Multi-Coating, resulting in an impressive 0.25-percent residual reflection and a filter free of any false reflections under any light angle. The transmission efficiencies of the long-pass filters (Yellow, Orange, and Red) peak at 98-percent, while the bandpass filters (Green, Blue, Dark Blue) achieve nearly 70-percent. This high efficiency, combined with the advanced coatings, provides maximum contrast and isolation of planetary details, even through smaller telescopes. The set includes filters with wavelengths ranging from 435nm to 610nm, catering to various observation needs.

Practical and Versatile Design

With a focus on practicality and versatility, the Baader Premium Color Filter Set is designed to fit almost all eyepieces on the market. Each filter cell features both male and female threads, allowing for stacking to achieve narrower pass bands or to combine with other Baader filters, such as the UV/IR-Cut filter. The 2-inch size is ideal for binoviewing, requiring only one filter for optimal performance. The filter cell also boasts the largest clear aperture available, ensuring complete freedom from vignetting at any focal length. With the Baader Premium Color Filter Set, you can experience the beauty of the night sky with unparalleled clarity and detail, making it an essential addition to any astronomy enthusiast's toolkit.
