And I'll return to Orion to study the features better.
Just wondering, does a nebula filter help to see the clouds better?

Well done Wey!!
A nebula filter works by reducing light other than those wavelengths emitted by the nebula so improving contrast. They are worth trying, bearing in mind I have found they work best with larger apertures. In an 8" the effects is noticeable, in a 12" if is very good, in my 20" it is often mind-blowingly good. The reason is that the sky background is pretty much darkened down to the same level regardless of the size of the scope while the larger aperture collects much more light from the target, so the contrast is much larger with larger scopes. Nevertheless, they are worthwhile trying at any size.
Personally I like the UHC style filters rather than the light pollution style ones.
Good luck with future searches!!
