About this product

Model:  ae_fltr_uhc_125
Part Number:  1.25 UHC Filter

Astro Essentials UHC Filter 1.25" / 2"

The narrowband UHC filter, like the O-III filter, isolates the two doubly ionized oxygen lines (496 and 501nm) in addition to the hydrogen-beta line (486nm) emitted by planetary and most emission nebulae.

The UHC filter permits superb views of objects like the Orion, Lagoon, Swan and other extended nebulae. It performs well in smaller aperture instruments owing to its greater light transmission than the O-III, yet still suppresses light pollution well.

The UHC filter is the best all-round dark-sky nebula filter as it offers decent gains on a wider variety of emission nebulae than the more selective OIII Filter
