The Neodymium Filter is made from optical-quality Schott glass and features a multi-coated optical surface to minimize reflection.
The fifth filter in the set is the UHT Oxygen III Filter. This filter is designed to enhance the view of emission nebulae, such as the Orion Nebula, by filtering out unwanted light and allowing only the oxygen III emission lines to pass through. The UHT Oxygen III Filter is made from optical-quality Schott glass and features a multi-coated optical surface to minimize reflection.
The final filter in the set is the UHT Hydrogen Alpha Filter. This filter is designed to enhance the view of hydrogen alpha emission nebulae, such as the Veil Nebula, by filtering out unwanted light and allowing only the hydrogen alpha emission line to pass through.
