Antlia OIII 4.5nm EDGE filters are designed to deliver 85% transmission at the 500.7nm line that provides you with the maximum signal to reveal the faintest OIII nebulae structures.

High transmittance for working with both long focal ratios and fast optical systems (as fast as f/3 or maybe even f/2.8)!

The reducer is designed with a three-element air-spaced lens structure, supporting full-frame imaging, effectively controlling unwanted vignette. The practical focal ratio of the Sharpstar 61EDPH when used with this reducer is f/4.5
