Telescopes & Astronomy

• Fast, wide-field 11” f/2.2 optical design with rare-earth glass for images free of false color, coma, and field curvature
• Large 43.3mm optimized image circle maintains pinpoint stars to the far corners of even the largest astroimaging sensors, while the usable field extends even further to 52mm for larger format sensors
• New Ultra-Stable Focus System (USFS) minimizes focus shift and mirror flop
• Integrated air-cooling system features a quiet, high-output 12V MagLev fan and vents with mesh filters to prevent dust ingress
• Common camera adapters (T-thread and M48) included for easy attachment to popular CCD and DSLR cameras

• Take beautiful images of deep-sky objects from light-polluted suburban locations with the Rowe-Ackermann Schmidt Astrograph 11 (RASA 11) using this light pollution suppression filter
• Custom designed to replace the RASA’s optical window, so you still get optimum optical performance even with the addition of the filter
• Selectively blocks unwanted light pollution while providing over 90% transmission at critical wavelengths
• Maintains a more neutral color balance than other light pollution imaging filters, perfect for imaging colorful nebulae and galaxies
• Every filter is individually tested for light transmission. A graph of test results for your specific filter is included for your reference

• The Celestron Universal T-Adapter connects a DSLR or SLR camera to a refractor for prime focus photography
• The adapter’s chrome barrel slides into any focuser that accepts 1.25” accessories
• T-Threads accept camera brand specific T-Ring (sold separately)
