Baader Planetarium
Baader Planetarium filters are essential for astrophotographers seeking clarity, accuracy, and detail in their celestial imaging. Designed with advanced multi-coatings and ultra-sharp bandpass curves, Baader filters offer excellent transmission and contrast, minimizing unwanted reflections, halos, and chromatic distortion. These filters are built to work seamlessly with CMOS sensors, for pinpoint star rendering and vibrant true-color results. Their Life-Coat™ durability guarantees long-term resistance to humidity, scratches, and delamination. But another standout option emerges for those seeking ultra-selective light suppression, especially in heavily light-polluted environments—the Optolong L-Ultimate 2" filter. How does it compare, and what unique advantages does it offer for deep-sky imaging? Let’s explore.
