Antlia Triband RGB Ultra Filter 2" for sale.

Perfect, like new condition, comes with the original crystal magnetic case and all packaging.

This is the V1 Triband Filter. The V2 adds H-beta (486.1nm), arguably not that important as it is a relatively weak signal compared to H-alpha and is often ignored in narrowband imaging.
Above 92% transmission of all the important wavelengths (Ha, S-II and O-III) also includes N-II for nitrogen rich nebulae.

Triband V2 sells for $329. So this one is priced accordingly.

$225 negotiable
