Description:
Antlia H beta and O III Filter for visual Observation and Photography, 1.25"
The
Antlia HB-OIII filter is engineered specifically for night visual
nebulae observation at a high contrast and Deep-sky astrophotography.
Its transmission is 90% or greater at critical wavelengths (H-Beta 486.1
nm, OIII 500.7 nm and OIII 495.9 nm). Youll notice much higher
contrast to observe Planetary Nebula, Supernova Remnant, Emission
Nebula, Diffuse Nebula, and extremely faint nebulae by the Antlia
HB-OIII filter.
When it is used for astro deep-sky imaging, it
enhances the details of the [O III] and H-beta emission lines with
astronomical cameras, DSLRs and DSLMs/MILCs.
Main Application and Performance:
Antlia
HB-OIII filter was coated for almost total suppression of unwanted
wavelengths with optical density (OD) 4 and the filter cut-off
wavelength is 300-1000 nm, which meets the spectral requirements of
photographic cameras and further enhances the suppression of the IR
region. Compared with visual filters with a cut-off depth of OD3@350-750
nm, it performs better to darken the sky background and make deep-sky
observation and photography of nebulae, star clusters, and galaxies more
easily.
The HB-OIII filter helps faint objects become much more
visible against the now darker background and produces near-photographic
views of the Veil, Dumbbell, and Orion nebula, among many other objects
under both light-polluted and dark skies.
Since human eyes are
less sensitive at night, large aperture telescopes are recommended to
gather light and funnel it into the observer´s eyes.
This triple line nebula filter allows visual observation and photography of nebulae with higher contrast.
