A better option still to use crossed polarisers (they are sold as a single filter, not expensive) where you can adjust how bright or dim an image you want.
But IMHO the best option is to use no filter at all and view the Moon in its first or last quarter if you want to see maximum detail. (For showing others the more-than-half-full Moon an ND-filter can be useful though.)

That’s also great advice. Thanks janos. I guess it all comes down to personal experiences and personal preferences. Thanks to all.
Collimator wise I notice that Ozscopes has a Saxon 1.25 Laser Collimator for $126 and a Skywatcher Newtonian Collimation Eyepiece for $60.
Just wondering 2 things - does the Saxon Laser Collimator make collimation that much easier than the Skywatcher $60 job?
And secondly I’m kind of sold on getting a Skywatcher 8” Dob as my first telescope and wondering if the Saxon Laser would be compatible with the Skywatcher dob?
