It allows OIII (35 nm Bandwidth) and H-Alpha (15 nm Bandwidth) wavelengths whilst blocking all other wavelengths
thus reducing the effects of light pollution, natural skyglow and moon light.
3: I have taken the liberty of analysing your image to see how well the filter worked.
Firstly I zoomed in on the nebula.
There is still considerable noise to be found,
so that suggests the filter with it's relatively wide bandwidth is still affected by moonlight.
I guess careful processing to remove (subtract) background gradients would help a lot.
Just for fun, removed some noise (after masking the neb), and then pushed the saturation a bit!
And remember I am new to this as well, we are all learning in this forum.
So keep em coming!

Wow! I like it! I must learn how that’s done! Thanks for the tip😃
