Thank you, what a pity, I may be looking for a halpha filter.
I wonder which of the 2 filters will give me better results.

I swapped my STC duo band with L extreme , its 1000 times better. Halo's are now present only on super bright stars.

I had noticed the l-extreme, its big flaw … it does not exist in FF  smile

Here's what I see on brighter stars with the STC Duo Narrowband.  I'm a bit bummed about the halos, but it's the only option that I have for my Fujifilm X-series cameras until I move to astro-dedicated equipment (eventually as the pennies accumulate).
