What is the bandpass of your Bob's filter?
Is the improvement with Bob's filter worth to make it?
Yes I have tried it on the Quark, I have no idea of bandpass, I have his 0.7a and 1.5a version and both are a waste of time, the PST etalon showing way more detail than both. To answer you last question, a straightforward no in my experience.
