BAADER H-BETA 5.5nm FILTER mirror Go2Nova® 8407+ V2 controller withThe Baader H Beta 5. 5nm filter is specifically designed for visual observation of faint emission nebulae under bright skies. Unlike H alpha filters, which are extremely difficult to use visually due to the lack of sensitivity of our eyes at the deep red end of the spectrum, H beta emissions are very close to where our eyes are most sensitive. Because of quantum mechanical coupling with H Alpha, you can see many of the same structures through an H
