Description
Highlights
- 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
