Antlia 7nm Prime Narrowband Filters

Antlia 7nm Prime narrowband filters are the entry point to Antlia narrowband imaging: H-alpha, OIII and SII filters with a 7nm bandpass, also offered together as the SHO 7nm Prime Filter Set. The wider bandpass collects signal quickly and tolerates a broader range of focal ratios than tighter filters.

They suit imagers starting out with a monochrome camera who want to shoot emission nebulae from suburban skies and build Hubble palette images.
