Celestron Light Pollution Imaging Filter for 11 RASA
Shipping Calculator
The Celestron Light Pollution Imaging Filter is custom-designed for the Rowe-Ackermann Schmidt Astrograph 11 (RASA 11), enabling you to capture high-quality deep-sky images even in light-polluted environments. This filter replaces the RASA’s optical window, ensuring optimal performance without affecting the telescope's functionality. With over 90% transmission at critical wavelengths, it blocks unwanted light pollution while maintaining a more neutral color balance than traditional filters—ideal for imaging colorful nebulae and galaxies.
Crafted with a 68mm clear aperture, this filter easily accommodates large sensors and ensures bright, detailed images. Its multi-layer dielectric and anti-reflective coatings reduce star halos and internal reflections, helping you capture sharp and vibrant celestial images. Built from durable machined aluminum and Schott B270 glass, it integrates seamlessly into the RASA 11 system.
Each filter is individually tested for light transmission, and a detailed graph showing the filter's performance is included. A protective plastic case is also provided for safe storage when not in use. This filter is an excellent addition for astrophotographers looking to overcome light pollution and achieve superior results with their RASA 11.
