  1. Optolong L-Ultimate 1.25” Narrowband Filter

    Purchased in error when I got trigger happy buying for a new setup. Heard lots of good things about the l-ultimate so bought one before finding out that I was going to get a mono camera it would be of limited use. Only purchased just over a month ago so hopefully this can find a new home for someone who will get use of it.
