Explore Scientific Nebula Filter 1.25″ CLS Range from 436nm to 536nm with peak at 488nm. Transmission 98.3% This is a general-purpose light-pollution reduction filter designed for observing the broad range of deep sky objects including nebulae and galaxies. The CLS does a good job of increasing contrast, providing a darker sky background. CA Residents: Prop […]

Explore Scientific Nebula Filter 2.0″ UHC Range from 458nm to 508nm with peak at 488nm. Transmission 96.7% UHC – This is an ultra-high contrast narrow-band filter, designed for observing the broad range of nebulae with 2.0-inch standard eyepieces or filter wheels. The bandpass is tighter than the CLS Nebula Filter, thereby blocking even more light […]

Explore Scientific Nebula Filter 1.25″ H-Beta Range from 478nm to 496nm with peak at 489nm. Transmission 94.5% H-Beta – Hydrogen is the most abundant element in the universe and many nebulae glow in the light of H-beta. This line filter blocks all other wavelengths (and thereby nearly all of the artificial light) and only the […]
