#Filters for nebulae

I don't think Oiii (narrowband) will work for visual at all
It does work.
In fact, the two OIII lines are the "main" lines for visual filtering
H-beta to a much lesser degree.
The only reason H-alpha doesn't work is because our rods cannot see it. Otherwise, it'd be great for visual
That's one of the reasons why people run night vision, because it unlocks H-alpha
How narrow
The narrowest you can go while capturing both lines
Single line doesn't work as well, looking at you Baader visual OIII.
With H-beta I think the filters are narrower, but those are for specific objects
Personal preferences of course play a role.
I'm hoping to get to see one in person before taking the plunge on my own filter
I recently bought a UHC filter I am not very experienced but I could see m57 shape decently well with dark adapted vision
Gives an edge only when dark adapted
yep, im in a bortle 9 but with my 8" f/5 i could clearly see the ring sort of blurred because of course it was too faint, but without any filters
I can see Ring pretty easily without a filter... Once I can actually find it
