Antlia 1.25" H-Beta and OIII Visual and Ph... $149.99
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. Description Antlia HB-OIII filter was coated with almost total suppression of optical density (OD)4 on unwanted wavelength and...

Antlia 3nm Narrowband H-Alpha (Ha) Pro Fil... from $344.25
Antlia H-alpha Pro narrowband filter optimizes the FWHM (full width half maximum) to 3nm bandpass. As the bandwidth becomes narrower, the 3nm Pro narrowband filters enhance contrast of emission targets by lowering the unwanted background signal. Antlia H-alpha 3nm Pro filters are designed to deliver 88% transmission at the 656.3nm line which provides you with the maximum signal and well defined nebulae structures. Conventional broader narrowband filters cause a heavy loss in transmission due to the strong Center Wavelength (CWL)-shift. We guarantee T>88% within 1nm range of the center bandwidth, which means that the 3nm Pro narrowband filter can guarantee...

Antlia ALP-Dual Band 5nm Golden Filter (AL... $474.95
The Antlia ALP-T dual band Golden 5nm filter is a dual line-pass filter which was designed to be used primarily with one-shot colour (OSC) cameras such as DSLR's or astronomical OSC cameras. It can also be used as a narrowband filter for monochrome cameras to save imaging time. Description The advanced multi-coatings on our ALP-T ultra dual band filter effectively isolates the red Ha and the blue-green OIII lines light from emission nebulae, with almost total suppression of optical density (OD)4.5 on unwanted wavelengths from light pollution, moonlight, and airglow. The result is that our ALP-T dual band 5nm filter...

Antlia LRGB V-series 1.25" Mounted (LRGB-V... $375.00
The Antlia LRGB-V Pro series filters are designed for monochrome cameras that use both CCD and CMOS sensors. Suitable sensors include KAF/KAI sensors, Sony IMX sensors, GSENSE and other sensor manufacturers. The LRGB-V Pro set is designed to approximately equalize the RGB response from the flux of red-sensitive CCD detectors. Description The result is that you achieve 1:1:1 equalized RGB exposures with the benefit of simplified post processing and reduced imaging time. New LRGB-V Pro series filters feature a carefully designed spectral gap between the green and red channels to minimize the effect of light pollution and to provide high...
