ANTLIA ENERGY REJECTION FILTER 130mm Leonardo Match Model：The Antlia 130mm Energy Rejection Filter is a multi coated dualband filter designed to reject the majority of light at both ends of the spectrum, with two narrow transmission windows of only 25nm half bandwidth around the H alpha and Calcium K & H lines.
