ANTLIA ENERGY REJECTION FILTER 150mm TOE storage of multiple pointing models

storage of multiple pointing models

The PW20-RC in its native format (no field flattening lenses) uses only a primary and secondary mirror with reflective coatings

giving an excellent field of view for galaxies

Be sure not to overtighten the ring's bolts or else the camera may be damaged

their agility (they can fly in most any direction at will)

ANTLIA ENERGY REJECTION FILTER 150mm TOE storage of multiple pointing modelsThe 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
