Antlia H-beta and OIII Filter for visual and photography - 1.25" Mounted
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 (OIII 500.7nm, OIII 495.9nm, and H-Beta 486.1nm). You’ll notice much higher contrast boost to observe Planetary Nebula, Supernova Remnant, Emission Nebula, Diffuse Nebula, and extremely faint nebulae by Antlia HB-OIII filter.
When it is used for Astro Deep-sky imaging, it enhances the details of the OIII and H-Beta emission lines with astronomical cameras and DSLRs.
