ANTLIA ENERGY REJECTION FILTER 150mm TOE Power 12V DC 2A 5The Antlia 150mm 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. This enables safe usage of H alpha and Calcium solar filters with telescopes by preventing as much extra energy as possible from entering the telescope. The 130mm ERF is suitable for use on telescopes
