Product series:
The eyepieces and the Barlow lens in the Cemax series have a coating optimised for the H-alpha wavelength of 656 nanometres. They are therefore ideal for observing the Sun with an H-alpha solar telescope and ensure maximum contrast in this area of application.
The minimisation of glare also makes these eyepieces and the Barlow lens very suitable for other bright objects, such as planets and the Moon. Here they also deliver excellent contrast.
