I asked that question about H-β August 2021 and the response was not what I expected.

S&T editors (Steve) (deepskyforum.com)

from the same source

"j.gardavsky here are some of my H-Beta nebulae as observed through my 6" F/5 achro and through the binoculars, but still not included the LBNs and the nebulae from the HII surveys from my last observin projects."
 

Thank you

The post that Don linked is really helpful. It is rather lengthy at 7 pages but worth the read.

Thanks

with assistance from gravity, swing on its own accord away from your target. This can be frustrating because first off you expect the scope to stay where you point it, and when it doesn’t that’s not good. Secondly, you may try to compensate for this behavior by adding in additional friction, but too much friction can make tracking erratic; also, not good.

Which is why I level my dob, not to your extent. Might have to upgrade my bubble level just because.
