Model:  ae_fltr_uhc_2_v2

The Astro Essentials UHC is a narrowband filter designed to accentuate the view of many emission and planetary nebulae.

The UHC Filter isolates the two doubly ionised oxygen lines (496 and 501nm) and the hydrogen-beta line (486nm) emitted by planetary and most emission nebulae.

The UHC is the best all-around dark-sky nebula filter as it works well with a wider variety of emission nebulae than the more selective OIII Filter.
