Description

Antlia SHO 4.5nm Narrowband EDGE Filters

Antlia SHO EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4.5nm bandpass. The suppression of optical density (OD)5 on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro series has been incorporated into the 4.5nm EDGE narrowband filters. The result is that these filters deliver superior SNR (signal to noise ratio) and better contrast in your images.

Antlia 4.5nm EGDE filters are designed to deliver high transmittance that provides you with the maximum signal to reveal the faintest of nebulae structures.

Conventional broader narrowband filters cause a heavy loss in transmission due to the strong Center Wavelength (CWL)-shift. We guarantee T>90% within 1nm range of the center bandwidth, which means that the SHO 4.5nm EDGE narrowband filters can guarantee high transmittance for working with both long focal ratios and fast optical systems. Blue-shift data shows that Antlia 4.5nm EDGE filters can be used with nearly all systems as fast as f/3 with minimal loss in emission signal and meets the requirements of fast optics.

Application and Performance:

High transmittance and narrow bandwidth to maximize contrast

Steep spectral profile minimizes halos around bright stars

A single substrate to eliminate internal reflections

Narrowband Objects: Emission Nebulae, Planetary, Wolf Rayet Nebulae and Supernova Remnants

Use in light polluted areas and dark sites

Extends imaging time when the moon is up

Antlia narrowband EDGE filters can be used down to f/3 systems with minimal loss of signal

All Antlia unmounted filters are edge blackened to eliminate internal reflections from stray light

Superior optical reliability reduces post image processing

This filter is only effective for deep sky objects that contain H-alpha, SII, OIII emissions
