Hello 

Anyone using one of these? Looking for opinions before I pull the plug and purchase one.

Thanks for reading

Get a Baader its a better filter, bandwidth is not the whole story with narrowband, the Optolong filters suffer from out of band light leakage and reflections.  Baader are my budget filter producer of choice.

I am in the position where I have both a Baader 7nm filter and an Optolong 7nm H-alpha filter running side by side on the same scopes and same cameras (sensors).  In fact I have the Oii and Siii of both too.  You will read a lot on forums about various filters, some of which is true, some of which is not.  I'm happy with both.
